I have a search suggestion component that is displayed under a TextField. whenever text is entered into the TextField the search suggestion component displays a list of possible matches based on the current entered text... I have more content under the TextField that gets pushed to the bottom whenever the Search suggestion gets populated with results. Is there any way to overlay the search suggestions over the content underneath it instead of pushing the content down? in HTML/css I would apply the position absolute and z-index css properties to the search suggestion component but this doesn't seem to be the case in Nativescript. I see that Nativescript does support the z-index css property but just applying that doesn't seem to do anything. It doesn't look like Nativescript supports the position property... Any idea how I can make this work/what i'm missing?
You have a couple quick options. One is to use a grid as mentioned in the comments. Set the views on the same row/col. This is the same as stacking views on the z axis. Or an absolute layout and use the same positioning of the views within that layout.

I am trying to implement custom tool tip in ag-grid, but the tooltip is partially visible.
For reference, i have source code present in Plunker. There are two ag-arid instances as an example. If you mouse over on first ag-grid on first column of last row, tooltip is partially visible.
is there a way to show full content of tooltip.

You need to set a height on the :host selector in your custom tooltip component. E.g. set it to 300px, then the tooltip should display above your mouse pointer when on the last row, allowing it be completely visible.
Demo.
I am trying to create a profile menu for my polymer website, something on the lines of github.com
If you notice,there is a triangular tip at the top of the menu.I am trying to create a similar triangle at the top of paper-listbox.
The problem I am facing is that the triangle seems to hide as soon as it gets out of the boundaries of paper-listbox.
I have create a jsbin to demonstrate my problem: http://jsbin.com/samaloqowu/1/edit?html,console,output
If you change the top property of the triangle (say -16px), it hides when it gets out of the listbox region. Please help me solve this CSS issue.
Short answer : No you can't.
Explanation : Because the dropdown content get encapsulated in a slotted element that gets styled inside the shadowRoot of the custom element you try to modify the behavior. And the paper-menu-button doesn't actually gives you a way to directly customize the slotted.
But there is a trick ! You can access the slotted through classic javascript. Just alter your connectedCallback function and add this line :
...
connectedCallback() {
super.connectedCallback();
this.$.profileMenu.$.dropdown.querySelector('.dropdown-content').style.overflow = 'visible';
...
}
...
This should do the trick, I agree this looks totally awful and trying to force and change the initial behavior of an element is not really recommended but well it seems to work, just make some tests when the element gets in a new context to see if anything breaks.
UPDATE (22/09/2017) :
Thinking of that again, I think this is a terrible idea to change this overflow to visible, I guess the polymer team has set the overflow to auto because if the list get long and you force the height of the element, the list will flow and be visible which is not really a dropdown anymore, but more like a full list display and that will mess with the general design purpose of your app. IMO when you start trying to mess with the inner properties of a custom element it means this element doesn't quench your requirement, and that it's time to make your own, especially when you try to modify the design of a custom element that has a design already implemented.
I'm creating a context menu for certain elements using a PopupPanel; the menu itself is going to be fairly large and complex. What I'm looking to do is to have a list of buttons, plus an image and some text, related to the element clicked.
My problem is that I'd like the buttons to always display directly under the clicked element, because that's convenient for the user; the issue is that when PopupPanel is near the edges of the screen, it automatically changes position to be fully visible, not aligning its left side to the element as usual. I like this behavior, but it moves the position of the buttons away.
So what I'd like to happen is: normally the buttons are on the left of the panel, the other stuff is to the right. When the panel is close to the right of the screen, I'd like the buttons to instead be on the right (and thus under the clicked element) and the other stuff on the left.
Is there a clever way to do this, either in GWT or better yet, using only CSS? PopupPanel itself doesn't seem to tell you when it's going to get flipped, sadly. The only solution I currently have is to manually check the position and width of the popup before showing it and adjust accordingly, but I'm hoping there's a better solution.
Here is what I suggest (based on my own implementation of a similar use case):
Have the position callback implementation accept references (in constructor) on:
PopupPanel element
element on which user right cliked
the content you put in the PopupPanel
Replicate (I know this not DRY but implementation is package private) the code from default position callback
When opening to the right invoke a method that changes the layout of your content (CSS based or otherwise)
I hope it helps. If you find something better let me know.
i need some pointers here because i don't really know what to look for.
The project is in gwt and is using gwtquery.
I have this page with some elements and when the mouse overs an element it changes showing additional infos, let's call it header. When the mouse goes out of the header (which has some buttons so it need to stay visible once shown) it returns invisible.
The problem is that when the header is made visible all the elements of the page change position because my element changes in dimension. What i wish to do is to keep the element in the same position and overlap the header over everything with z-index.
It's not about GWT at first hand. It's mostly about general concepts of elements positioning and layout building for html pages. You should start from something like http://www.w3schools.com/Css/css_positioning.asp
And then find the appropriate tools in GWT framework or in third party libraries that are available.
I'm trying to make a Flex (Advanced)DataGrid component with some mechanism where the user can toggle the visibility of the columns. I've crudely implemented this by reading in the columns into the right-click menu, and when a column name is selected here, the visibility is toggled. It works, but it's not the most elegant solution.
Specifically, I'm trying to emulate the "datagrid" that Mozilla Thunderbird uses to display emails. Here is an image:
In the upper right, there is an icon over the scroll bar. If there is no scrollbar, the icon remains in the same place. When clicking the icon, it opens up a menu that shows all the possible columns, with the visible ones having a check mark next to them, like this:
Also, the scroll bar always appears under this button, never "pushing" it over into it's own column.
I'd like to re-create this in Flex. I believe the menu part and creating a column with a button headerRenderer is easy enough. But I can't figure out how (if at all possible) to do this with the scrollbar, because the scrollbar always seems to be "its own column". Any ideas or help would be appreciated. Thank you.

One dirty solution comes to mind. Create a component based on Canvas, then add an AdvancedDataGrid by overriding createChildren. Override updateDisplayList as well and add a button like the one in Thunderbird to the upper right of the Canvas. This will cause the button to appear over the DataGrid. Problemo solved?
