Dear nevzatopcu,

There's no such possibility with some @Input() to change the classes inside mdb-tabset component, but it's possible to achieve such behavior with @ViewChild() decorator.

Just grab the mdb-tabset element with @ViewChild(), and then change the listGetClass and tabsGetClass properties to your desired classes.

Please take a look at the below .ts code:

 @ViewChild('staticTabs') tabs: TabsetComponent;

  ngAfterViewInit() {
   setTimeout(() => {
     this.tabs.listGetClass = 'col-md-2';
     this.tabs.tabsGetClass = 'col-md-10';
   }, 0);
  }

Best Regards,

Damian
