DropDown
I'm using Bootstrap-vue. I need to make the b-dropdown-item-button wrap the text it's showing. How could I do that?
<template>
<b-dropdown menu-class="py-1" text="··· Actions">
<b-dropdown-item-button>Delete</b-dropdown-item-button>
</b-dropdown>
</template>
The dropdown has a min-width andwhite-space: nowrap` set by default, so you need to apply some css to override this.
window.onload = () => {
new Vue({
el: '#app'
})
}
<link type="text/css" rel="stylesheet" href="//unpkg.com/bootstrap/dist/css/bootstrap.min.css" />
<link type="text/css" rel="stylesheet" href="//unpkg.com/bootstrap-vue#latest/dist/bootstrap-vue.min.css" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.6.10/vue.js"></script>
<script src="https://unpkg.com/bootstrap-vue#2.0.4/dist/bootstrap-vue.min.js"></script>
<style>
/* Adding it here since it wasn't working in the snippet CSS */
body { padding: 1rem; }
/* Removes the min-width on the dropdown-menu and sets the width to 100% of the parent */
.wrap-dropdown {
width: 100%;
min-width: 0;
}
/* applies white-space: normal to all tags inside the dropdown-menu */
.wrap-dropdown * {
white-space: normal;
}
</style>
<div id="app">
<b-dd menu-class="py-1 wrap-dropdown" text="··· Actions">
<b-dd-item-btn>Delete</b-dd-item-btn>
<b-dd-item-btn>
This text is really long
</b-dd-item-btn>
</b-dd>
</div>

I am self-studying Vue.js. I am using v-bind to add the highlight class to the span element, which is supposed to add newBorder style to the element, but the style doesn't get applied.

Appreciate it if you can point out my mistake.
Thanks
Just change the class binding the array syntax instead of object :
<span v-bind:class="[loadClass,highlight]">

im currently digging through the github page, but Im unable to figure out how to set the tabSize property on my prism editor, if anyone has any experience and is willing to share it I would greatly appreciate it!
I will answer here as I placed in code snippet for you to play with.
There is a problem on the umd script where it cannot recognise tabSize as a valid props.
Therefore, you can use tab-size to overcome this.
P.S. move tab size to be part of vue data to avoid complaining the type.
Here is the code snippet for you to test it.

/* you must provide font-family font-size line-height. Example:*/

i'm using bootstrap-vue and i have a multi level drop down menu (for categories) . this is official site example :
https://bootstrap-vue.org/docs/components/dropdown
<b-dropdown id="dropdown-1" text="Dropdown Button" class="m-md-2">
<b-dropdown-item>First Action</b-dropdown-item>
<b-dropdown-item>Second Action</b-dropdown-item>
</b-dropdown>
but i don't know how to create a multi level menu (i copy drop downs inside each other but it does not work) ! it has only 1 level drop down example ! how can i create a multi level one ?
tnx
So as I mentioned in my comments you can wrap b-dropdown events and do something custom like this:
window.onload = () => {
new Vue({
el: '#app',
data() {
return {
name: 'BootstrapVue',
isDropdown2Visible: false
}
},
mounted: function () {
this.$root.$on('bv::dropdown::show', bvEvent => {
if(bvEvent.componentId === 'dropdown-2') {
this.isDropdown2Visible = true;
}
})
this.$root.$on('bv::dropdown::hide', bvEvent => {
if(bvEvent.componentId === 'dropdown-2') {
this.isDropdown2Visible = false;
}
if(this.isDropdown2Visible) {
bvEvent.preventDefault()
}
})
}
})
}
body { padding: 1rem; }

<script src="https://unpkg.com/bootstrap-vue#2.21.2/dist/bootstrap-vue.min.js"></script>
<div id="app">
<b-dropdown id="dropdown-1" text="Dropdown Button 1" class="m-md-2">
<b-dropdown-item>First Action 1</b-dropdown-item>
<b-dropdown-item>Second Action 1</b-dropdown-item>
<b-dropdown id="dropdown-2" text="Dropdown Button 2" class="m-md-2">
<b-dropdown-item>First Action 2</b-dropdown-item>
<b-dropdown-item>Second Action 2</b-dropdown-item>
</b-dropdown>
</b-dropdown>
</div>
You can try something like this
This snippet contains logic for one level menu.You can edit code as
per your requirement
JSBin Link
new Vue({
el: "#app",
data: {
menu: [
{ title : 'one'},
{ title : 'two'},
{ title : 'three',showSubMenu : false,
children : [
{ title : 'four'},
{ title : 'five'},
]},
]
},
methods : {
toogleItem(index){
if(this.menu[index].children){
if(!this.menu[index].showSubMenu){
this.menu[index].showSubMenu = true
} else {
this.menu[index].showSubMenu = false
}
}
}
}
})
.sub-menu{
position: absolute;
min-width: 10rem;
padding: .5rem 0;
margin: .125rem 0 0;
font-size: 1rem;
color: #212529;
text-align: left;
list-style: none;
background-color: #fff;
background-clip: padding-box;
border: 1px solid rgba(0,0,0,.15);
border-radius: .25rem;
}

I need some help. I am trying to style bootstrap vue pagination and I am not able to achieve it. The only thing I was able to achieved was to moved the pagination 50% to the left. I can not style the ul, li and the button inside the li such as changing background for ul, li and button, text color and etc. I even use class name on them, but nothing is working.
var app = new Vue({
el: '#app',
data: () => ({
currentPage: 1,
rows: 50
}),
})
.pagination {
margin-left: 50%;
ul {
text-align: right;
li {
float: right !important;
}
}
.page-item {
color: $color-red;
}
.page-link {
color: $color-red;
}
}

compile your sass file, and inspect the elements to get to the selectors
var app = new Vue({
el: '#app',
data: () => ({
currentPage: 1,
rows: 50
}),
})
.pagination {
margin-left: 50%;
}
.pagination ul {

I copied an example from the dojo site using Borderlayout. However, when I load in the browser , the entire data is shown for all the section . Then after a few second the content is refersh and the data is displayed correctly.
here is code that i copied . Thanks for your help
<head>
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/dojo/1.3/dijit/themes/tundra/tundra.css">
<style type="text/css">

{ width: 100%; height: 100%; }
</style>
</head>
<body class="tundra ">
<div dojoType="dijit.layout.BorderContainer" design="sidebar" gutters="true"
liveSplitters="true" id="borderContainer">
<div dojoType="dijit.layout.ContentPane" splitter="true" region="leading"
style="width: 100px;">
Hi
</div>
<div dojoType="dijit.layout.ContentPane" splitter="true" region="center">
Hi, I'm center
</div>
</div>
</body>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/dojo/1.3/dojo/dojo.xd.js"
djConfig="parseOnLoad: true">
</script>
<script type="text/javascript">
dojo.require("dijit.layout.ContentPane");
dojo.require("dijit.layout.BorderContainer");
</script>
<!-- NOTE: the following script tag is not intended for usage in real
world!! it is part of the CodeGlass and you should just remove it when
you use the code -->
<script type="text/javascript">
dojo.addOnLoad(function() {
if (window.pub) {
window.pub();
}
});
</script>
This looks a bit upside down : you should put your javascripts in the head section and load the dojo libraries in first place. That's not your problem though.
What happens is that when the page loads, dojo loads all the modules that you "dojo.require", then parses all your tags containing the attribute "dojoType" and processes them for rendering, and this takes time.
So the flickering that you're seeing is the difference between the page before and after the widgets are parsed.
You should add a preloader div and hide it once the page is parsed (see this example).
This is what it would look like for your example :
<html>
<head>
<title>Preloader example</title>

disable parseOnLoad and manually add event to parse widgets for ie.
