I\'m trying to customize mat-select with multiple checkboxes. for some reason the panel get wrong min-width as below:
and I don\'t know where its calculating t
Try this way : define a panel class for your mat-select in the code and then in the global/app styling file just add:
.panel-class-name .mat-select-panel { // add your styling here }
It worked for me to add some component specific styling for material components.
