To improve the look and style I changed the CSS a little:
.inputStyle .q-field__inner .q-field__control
{
padding-right: 0;
min-height: unset;
}
.inputStyle .q-field__inner .q-field__control .q-field__control-container
{
margin-top: 16px;
margin-bottom: 16px;
min-height: unset;
}
.inputStyle .q-field__inner .q-field__control .q-field__control-container .q-field__native
{
padding: 0;
padding-right: 12px;
min-height: unset;
max-height: 130px;
overflow-y: auto;
overflow-x: hidden;
}
Centres the scroll bar and adds space above and below the chips and only shows scroll bar when you go past the max height. Starts off with the same height as normal at 56px.
