I am currently experimenting with building a compact search box that offers suggestions using the vue 3 boostrap library. I am aiming to have the suggestions box float on top of the following div without pushing it down. Despite trying to manipulate the z-index, I have not been successful in achieving this.
You can find a code example on Codepen: https://codepen.io/vue_novice/pen/wvxbyMQ
<div id='app'>
<b-container fluid>
<b-row align-h="center">
<b-col cols="4">
<h1 class="text-center mt-4 mb-4">My Search</h1>
<b-input-group size="lg">
<b-form-input placeholder="Type Something"></b-form-input>
<b-input-group-append>
<b-button variant="primary">🔍</b-button>
</b-input-group-append>
</b-input-group>
<b-list-group>
<b-list-group-item>Suggestion 1</b-list-group-item>
<b-list-group-item>Suggestion 2</b-list-group-item>
<b-list-group-item>Suggestion 3</b-list-group-item>
<b-list-group-item>Suggestion 4</b-list-group-item>
</b-list-group>
</b-col>
</b-row>
<b-row align-h="center">
<b-col cols="6">
<h1>I want to be hidden behind the Suggestions 😊</h1>

</b-col>
</b-row>
</b-container>
</div>
How can I modify the code to ensure that the suggestion box in the search field overlaps the text below it on the z-axis?
