Expansion panels
The v-expansion-panel component is useful for reducing vertical space with large amounts of information. The default functionality of the component is to only display one expansion-panel body at a time; however, with the multiple property, the expansion-panel can remain open until explicitly closed.
Usage
Expansion panels in their simplest form display a list of expandable items. You can either declare the markup explicitly, or use the title and text props.
<v-expansion-panels>
<v-expansion-panel
title="Title"
text="Lorem ipsum dolor sit amet consectetur adipisicing elit. Commodi, ratione debitis quis est labore voluptatibus! Eaque cupiditate minima"
>
</v-expansion-panel>
</v-expansion-panels>API

Examples
Props
Variant
There are four different variants of the expansion-panel. Accordion expansion-panels have no margins around the currently active panel. Inset expansion-panels become smaller when activated, while poput expansion-panels become larger.
Disabled
Both the expansion-panel and its content can be disabled using the disabled prop.
Model
Expansion panels can be controlled externally by using the v-model. You will need to set a value on each panel, so that you can refer to them outside the component. If the multiple prop is set, then the v-model value will be an array.
Readonly
readonly prop does the same thing as disabled, but it doesn’t touch styles.
Misc
Advanced
The expansion panel component provides a rich playground to build truly advanced implementations. Here we take advantage of slots in the v-expansion-panel-title component to react to the state of being open or closed by fading content in and out.
Custom icon
Expand action icon can be customized with expand-icon prop or the actions slot.
