Incorporate the list seamlessly into the remaining content of the page

I am currently developing a Vue component that utilizes an API call to search for a list of cities based on user input. My challenge is ensuring that the displayed list does not overlap with the header component, specifically overlapping the image of the sky in the background. I have attempted to use z-index without success.

Any alternative solutions or suggestions for implementation are greatly appreciated. I have also tried using a dropdown menu, but encountered issues with writability.

Update: apologies for forgetting to include the code snippet.

<!--template-->
<div class="input-city">
    <input  v-model="input" type="text" ref="citySearch" />        
    <div class="cities-list">
        <span
            v-for="city in results"
            :key="city.id"
            @click="setCity(city)"
            class="city-item"
        >
            {{ city.name }}, {{ city.region }}, {{ city.country }}
        </span>
    </div>
</div>
// styles
.input-city {
    display: flex;
    flex-direction: column;
}

.cities-list {
    display: flex;
    flex-direction: column;
}

.city-item {
    border: 1px solid black;
}

If you're searching for a specific feature, it's called absolute positioning, and it can be accomplished by setting the element's style property to either absolute or fixed.

Essentially, when an element is taken out of what's known as "flow content," the other flow content elements act as if the absolute positioned element isn't there.
The exact position of the absolute positioned element is in relation to

  • the closest positioned ancestor if position is set to absolute
  • the closest viewport if position is set to fixed.

In your scenario, this code snippet should do the trick:

.input-city {
  position: relative;
}
.input-city .cities-list {
  position: absolute;
  top: 100%;
}
  1. position: relative on .input-city establishes that element as the nearest positioned element for .cities-list.
  2. position: absolute removes .cities-list from content flow.
  3. top: 100% provides it with a top margin equal to its parent's height.

A common styling solution in such cases involves giving the overlapping element a background-color and a box-shadow to differentiate it from the overlapped content (but these are implementation specifics).

To delve deeper into how position (a fundamental CSS concept) functions, consider starting with this article: CSS Positioning 101.
