Establish the lowest possible height for Angular Material Expansion Panel Content

Is there a way to specify a minimum height for the content of an Angular Material expansion panel when it is open? I have searched for examples on setting the expandedHeight and collapsedHeight for the header, but not for the content itself. The Angular Docs mention MatExpansionPanelContent here: https://material.angular.io/components/expansion/api#MatExpansionPanelContent, but I couldn't find any properties that allow setting a minimum height.

I am facing an issue with a side navigation overlapping a component with a mat accordion. The side navigation is getting compressed based on the size of the expansion panel inside the accordion. Below is how my HTML is structured:

<div class="mtTool" fxLayout="row" fxLayout.sm="column">
<div fxFlex="65" >
    <mat-sidenav-container>
        <mat-sidenav #sidenav mode="over" closed>
            <app-mt-mark-form [mtp]="mtp" ></app-mt-mark-form>
        </mat-sidenav>
        <mat-sidenav-content>
            <app-mt-ticket-list></app-mt-ticket-list>/* this has the mat accordion
        </mat-sidenav-content>
    </mat-sidenav-container>
</div>
<div fxFlex="35">
    <app-mt-map></app-mt-map>
</div>

Thank you!

Answer №1

I decided to encapsulate the content within a div and specify a minimum height using CSS. So far, everything seems to be functioning properly.

<mat-expansion-panel>
<mat-expansion-panel-header>
    <mat-panel-description>
       <h2>HEADER</h2> 
      </mat-panel-description>
</mat-expansion-panel-header>
<div class="ticketContent">
...content here
</div>

CSS Code:

.markTicketContent{
min-height: 70vh;

}
