I have the following menu setup, and I think you can see the problem immediately:


As you can possibly see, I have a v-app-bar which contains the menu, and a main content area.

The v-menu is being overlapped by the v-card in the content of the page.

Trying to set the z-index property on v-menu did not help.


Some digging rendered interesting information I did not know about z-index: some objects behave differently, there is different z-index stacks which are not related, etc.

I recommend this excellent introduction to things you should know about z-index .


The solution

You need to set a style in v-app-bar. z-index is not enough, you also have to set position: relative for it to render correctly:

<v-app-bar fluid color=“white“ elevation=“2″ style=“position: relative; z-index: 3″>


after the fix the menu now overlaps the v-card in the main content – as it is expected by the user who wants to use the menu.

The full markup (abridged)

     <div class=“box box-default“ style=“z-index:2″>
       <v-content >
         <v-container fluid>
       <v-app-bar fluid color=“white“ elevation=“2″ style=“position: relative; z-index: 3″>
     <v-menu attach offset-y transition=“v-scale-transition“>
       <template v-slot:activator=“{ on }“>
         <v-icon small left color=“primary“>fa fa-bars</v-icon>
       <v-list dense>
         <v-list-item :to=“{ name: ‚Help‘ }“>
           <v-icon left small>fa fa-question-circle</v-icon>Help
       <v-divider class=“my-0″></v-divider>

Note: the main content is being rendered in router-view, (I use vue-router for the upcoming picockpit version).

How did I find this solution?

I used Google Chrome’s DevTools and went manually through each wrapping element set, setting z-index and experimenting with different positions, until hitting on the right element to apply it to.

Then I went into vue’s markup, and applied a style of “background-color:red”, and checked whether I had located the correct element.

I tried setting a z-index property on the vue element I identified (v-app-bar which renders to <header>), this however was not rendered correctly. Therefore I set the z-index directly in the style, this is applied correctly.
