Vuetify - Programatically trigger v-text-field animation

When a v-text-field component is populated with text or focused by the user, an animation triggers to move the label text up and to the left, and the field changes color like so:
I am trying to build a multi-select component using the v-text-field component. The reason I can't use a v-select is that my data-set is nested which is currently unsupported.
Is there a way to programmatically trigger this animation without having to focus the field?
I found a workaround that suits my purposes. There is a prop on the v-text-field component called persistent-placeholder which forces the label into the post-animated state when true.

Vue.js - custom photo grid with custom overlay

how can i make a photos grid (each photo is a card) with custom overlay.
when the user hover the photo, he will see the details overlay.
so the user will see the photo and details on it.
i tried to do this with "Beautify" and "Bootstrap-Vue"
and did not succeed.
example for what i look for: example website
Just build your grid of items - styling them with bootstrap "Card" component and grid system to make it as a grid.
Then just use this custom vue component with v-for and then bind #mouseover + #mouseleave on this element to change the state of hovered property or whatever you like to call it. Then just change your text or structure in your component according to hovered state.

Xamarin Forms changing the size of a viewcell dynamically

Using a Xamarin Forms ListView with a custom ViewCell, is it possible to have a list item expand based on an event? Please ignore the orange lines, but reference the below picture...
Regular cell not expanded
User has tapped the triple dots causing the ViewCell to expand to show additional content
Is this possible? What is the technique to make that work?
You can have containers or elements inside your viewcell whose Visibility can be controlled based on the click. You will have to re render the elements once its expanded or collapsed for the viewcell to resize. Or else you will have the Viewcell being the size it was initially rendered, but the contents inside it overflowing.

Show hide content in List item in Windows Phone 8.1

I'm developing WP8.1 app in that I need to show some content with show/hide functionality. First 2 lines will be displayed and once clicking on that item the remaining content should expanded and display. How we can achieve this in WP8.1
In order to show or hide you have to go for binding.
And to expand the content, have your DataTemplate as StackPanel and set the Height property of TextBlock (through binding) with the value that is needed to display two lines.
And on tap of the item, just get the selectedItem instance and Increase the height property or set to auto
To know about binding see here http://msdn.microsoft.com/en-us/library/windows/apps/cc278072(v=vs.105).aspx
you can use visibility and collapsed
like that
myimage. visibility =visibility.visible;
you can control with this way

Can I edit the UINavigationItem's title from within the app?

So I want the ability to change the title of the UINavigationItem from within the app. To be more specific, I want to be able to tap the title on the navigation bar and have it go into edit mode; where I can type in a new title. Is there any way to do this?
It's quite possible and not very hard in fact. Here are the simple steps:
Navigation item allows for custom views in its title
Add a view with a label similar to that of the native navigation item
Add a transparent button (custom button) on top of the label
Add a hidden text field on top of the button
When the button is pressed, hide the label and show the text field - focus on the text field (becomeFirstResponder)
You are in editing mode: now track for "Return" key being pressed, and once that happens set your label text to what has been entered, resign first responder from the text field and hide it, then show the label
If you adjust all the properties of the UI components it will look like your navigation item supports inline editing!
