Is there method like onAfterLoad() or onLoad() for Multicombo as I have to do axios call on that event after the Multicombo field gets rendered.
As list is inside the multicombo, so it's possible to use events of the list.
I recommend using waitData.
onAfterLoad is possible to use, but it will be not a good way because of:
if using onAfterLoad event + attachEvent,so attachEvent can lose the first data loading because it's initialized after init the component. If using on+onAfterLoad inside the body of multicombo , so it will break multicombo
