Dropdown and MultiSelect on expand event

[fairking]

I am missing a small feature on the Dropdown and MultiSelect components. I would like to load a list of options when the dropdown is being expanded first time, not on page load.
So I can see if I pass the selected value as `{ id: 123, name: "Bla-bla" } the name is already included so it will be visible without necessity of loading the list.

1. Currently if value is present but list is not loaded Dropdown shows empty field (even when my name is present in the value object).
2. Would be nice to have a spinner on the expanded area while items are loaded (not a big deal).
3. It might be an event on-expand or something. So when that happens I can check if options are loaded. If they're not I can load the list of options.

Please let me know what do you think guys.

We'll add show and hide events to both of the components.

Thanks @cagataycivici

Loading the list on expand I meant loading from the server, so the will be some delay when options are expanded. I think you can just add an event and I will test the functionality and then let you know if there anything else needs to be done. I think this feature will benefit and will be interesting for everyone. Thanks.

I agree, once you confirm that it works we can later add a loading prop with a loading icon so the users can be notified during loading process.

There are now;

• before-show
• before-hide
• show
• hide

Thanks @cagataycivici I will be in touch as I am going to create such functionality to load dropdown options only when user expands it.
