How to create a customized Select.Item from native-base? - react-native

I am using Select from native-base and I'm having problem with trying to customize the selectable options from Select.Item.
react-native: 0.70.5,
native-base": "^3.4.25
<Select>
<Select.Item value="one" label="one" />
</Select>
where it will only render the label, which expects a string. I am not able to render any other component from Select.Item
what I'm trying to achieve looks a lot like the picture below:
Desired Select.Item

Edit: not a solution as it breaks the component value. You have to use leftIcon and rightIcon properties instead
You can use the label attribute to customize the item content.
Something like:
<Select>
<Select.Item
value="one"
label={
<Row>
<Icon as={MaterialCommunityIcons} name="information" />
<Text>one</Text>
</Row>
}
/>
</Select>
In my opinion, the attribute name is misleading. You can also use leftIcon and rightIcon properties on Select.Item. If you can't achieve the customization level you want with these, I'm afraid you will have to create your own Select component based on ActionSheet elements.
Note that this will not be web compatible, so if you need web support it won't be an option. I'm also not sure to which extent other components are supported within this item element.

How to change HTML tags of the component dynamically after click in Vue3 composition-api?

I am writing my first app in Vue3 and I use composition-api with script setup.
Using v-for, I create components that are inputs (CrosswordTile) that make up the crossword grid.
A problem appeared during the implementation of the field containing a clue to the password.
Since the text doesn't allow text to wrap, I wanted to dynamically change the tag to after a click.
Function in parent component where I handle logic after click that change tile type works fine, but I need to change tag of "target" to and set maxLength to a different value.
If it would help here is whole code on github: https://github.com/shadowas-py/lang-cross/tree/question-tile, inside CrosswordGrid.vue.
function handleTileTypeChange(target: HTMLInputElement) {
if (target && !target.classList.contains('question-field')) {
addStyle(target, ['question-field']);
iterateCrosswordTiles(getNextTile.value(target), removeStyle, ['selected-to-word-search', 'direction-marking-tile']);
} else if (target) {
removeStyle(target, ['question-field']);
if (getPrevTile.value(target)?.classList.contains('direction-marking-tile')) {
iterateCrosswordTiles(
target,
addStyle,
['selected-to-word-search', 'direction-marking-tile'],
);
}
}
TEMPLATE of ParentComponent
<div
class="csw-grid"
#input="handleKeyboardEvent($event as any)"
#mousedown.left.stop="handleClickEvent($event)"
#click.stop="">
<div v-for="row in 10" :key="row" class="csw-row" :id="`csw-row-${row}`">
<CrosswordTile
v-for="col in 8"
:key="`${col}-${row}`"
#click.right.prevent='handleTileTypeChange($event.target)'
/>
</div>
</div>
I tried to use v-if inside CrosswordTile, but it creates a new element, but I just need to modify the original one (to add/remove HTML classes from it basing on logic inside CrosswordGrid component).
How can I get access to the current component instance properties when using the composition API in script setup or how to replace the tag dynamically?
:is and is doesn't work at all.

React Native Styling: how to style "sub element"?

In web css, we can set css for sub element. Example:
<div class="test">
<p>abc</p>
</div>
And we can set the <p> css by:
.test p {
font-size:20px;
}
Now in React Native, I have this:
<View style={myStyle.test}>
<Text>abc</Text>
</View>
How we can set the <Text> style by myStyle.test?
Actually you can't use like css children, you have to set a custom style for each element that you wanna use.
CSS in react native is just a subset of web css and it doesn't allow you to do what you do in webCss. All you have is inline css. So you have to style them separately. You can avoid repeating by defining a common style object and pass that instead of repeating.
You can check out this library as well:
https://github.com/vitalets/react-native-extended-stylesheet
According to docs
All of the core components accept a prop named style. The style names and values usually match how CSS works on the web, except names are written using camel casing, e.g. backgroundColor rather than background-color
Now cascading is not supported in react-native, yo =u have to provide a style prop to each element for it to be styled.

How do you wrap an achor tag in Vue2?

I am using Vue 2 and I am using an anchor tag as a "button" (for styling purposes with an svg).
The drawback of using an anchor tag in this way is that you can't disable it in the same way as a button.
I would like to make a vue component that simply wraps an anchor tag. I would like the component to pass all properties of the custom component onto the child anchor tag so that someone can use it like this:
<custom-comp id="closeButton" title="Close" class="c-btn" #click="close" :disable="true"></custom-comp>
I want to intercept the click on the child anchor tag and only emit that if the component is not disabled.
How can I achieve this?
You can't. disable property is used only in form elements. What you're looking for here is to use v-if:
<a id="closeButton" title="Close" class="c-btn" #click="close" v-if="isConditionMatched">
Only show if isConditionMatched returns true
</a>
Or, conditionally you can use return false statement inside your method:
close() {
if(!isConditionMatched) return false;
// continue your close function
}

Change element type at runtime

Is it possible to dynamically define the type of an element inside a custom components template at runtime?
I'd like to avoid duplication of the inner contents of the button and a element in the following example:
<template>
<button if.bind="!isLinkBtn">
<span class="btn-icon">${icon}</span>
<span class="btn-text">${contentText}</span>
</button>
<a if.bind="isLinkBtn">
<!--
The content is a 1:1 duplicate of the button above which should be prevented
somehow in order to keep the view DRY
-->
<span class="btn-icon">${icon}</span>
<span class="btn-text">${contentText}</span>
</a>
</template>
Is it possible to write something like this:
<template>
<!--
The type of element should be defined at runtime and can be a standard HTML "button"
or an anchor "a"
-->
<element type.bind="${isLinkBtn ? 'a' : 'button'}">
<span class="btn-icon">${icon}</span>
<span class="btn-text">${contentText}</span>
</element>
</template>
I'm aware of dynamic composition with <compose view="${widget.type}-view.html"></compose> but as far as I know, this won't allow me to create default HTML elements but only custom components, correct?
I've asked this question on the Aurelia Gitter where Erik Lieben suggested to use a #processContent(function) decorator, replace the content within the given function and return true to let Aurelia process it.
Unfortunately I don't know how to actually apply those instructions and am hoping for some alternative approaches here or some details about how to actually accomplish this.
Edit
I've created a corresponding feature request. Even though possible solutions have been provided, I'd love to see some simpler way to solve this ;)
When you want to reuse HTML snippets, use compose. Doing so does not create a new custom element. It simply includes the HTML at the location of each compose element. As such, the view-model for the included HTML is the same as for the element into which it is composed.
Take a look at this GistRun: https://gist.run/?id=36cf2435d39910ff709de05e5e1bedaf
custom-link.html
<template>
<button if.bind="!isLinkBtn">
<compose view="./custom-link-icon-and-text.html"></compose>
</button>
<a if.bind="isLinkBtn" href="#">
<compose view="./custom-link-icon-and-text.html"></compose>
</a>
</template>
custom-link.js
import {bindable} from 'aurelia-framework';
export class CustomLink {
#bindable() contentText;
#bindable() icon;
#bindable() isLinkBtn;
}
custom-link-icon-and-text.html
<template>
<span class="btn-icon">${icon}</span>
<span class="btn-text">${contentText}</span>
</template>
consumer.html
<template>
<require from="./custom-link"></require>
<custom-link content-text="Here is a button"></custom-link>
<custom-link is-link-btn.bind="true" content-text="Here is a link"></custom-link>
</template>
You may want to split these into separate elements, like <custom-button> and <custom-link> instead of controlling their presentation using an is-link-btn attribute. You can use the same technique to reuse common HTML parts and composition with decorators to reuse the common code.
See this GistRun: https://gist.run/?id=e9572ad27cb61f16c529fb9425107a10
Response to your "less verbose" comment
You can get it down to one file and avoid compose using the techniques in the above GistRun and the inlineView decorator:
See this GistRun: https://gist.run/?id=4e325771c63d752ef1712c6d949313ce
All you would need is this one file:
custom-links.js
import {bindable, inlineView} from 'aurelia-framework';
function customLinkElement() {
return function(target) {
bindable('contentText')(target);
bindable('icon')(target);
}
}
const tagTypes = {button: 'button', link: 'a'};
#inlineView(viewHtml(tagTypes.button))
#customLinkElement()
export class CustomButton {
}
#inlineView(viewHtml(tagTypes.link))
#customLinkElement()
export class CustomLink {
}
function viewHtml(tagType) {
let result = `
<template>
<${tagType}${tagType === tagTypes.link ? ' href="#"' : ''}>
<span class="btn-icon">\${icon}</span>
<span class="btn-text">\${contentText}</span>
</${tagType}>
</template>
`;
return result;
}
Sorry, I was doing 2 things at once while looking at gitter, which I am not good at apparently :-)
For the thing you wanted to accomplish in the end, could this also work?
I am not an a11y expert or have a lot of knowledge on that area, but from what I understand, this will accomplish what you want. The browser will look at the role attribute and handle it as a link or button and ignores the actual element type itself / won't care if it is button or anchor it will act as if it is of the type defined in role.
Then you can style it like a button or link tag with css.
<a role.bind="type"><span>x</span><span>y</span></a>
where type is either link or button, see this: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_link_role

Has TabBarIOS an Icon-Only Style?

I'm currently playing with the TabBarIOS-Component. It works perfectly but what I'm missing is a Icon-Only Style like TweetBot. Is there a way to tell TabBarIOS that I don't need/want the title?
You must explicitly set the title to an empty string:
<TabBarItem title="" />
