New prop for DropDownMenu: displayMemberOnLabel

[Sly777]

Prop Name: displayMemberOnLabel
Default Value: null
Prop Type: String

To show different value on selected item (for example; when you want to show country names on list but country code on Label, you can use this)

I added to SelectField too, @oliviertassinari

[oliviertassinari]

Thanks.
I think that we should call this property labelMember to stay coherent with valueMember and displayMember.
Could you set a default value to text for the property in the getDefaultProps() method and add this property in the documentation?

[Sly777]

Hey @oliviertassinari. i updated everything as you want.

[oliviertassinari]

displayValue = selectedItem[labelMember];
May be better

[oliviertassinari]

@Sly777 Thanks, it's almost ready to be merged 👍

[Sly777]

@oliviertassinari i updated doc & select-field. If it's still not okay, i can restore to back ;)

[oliviertassinari]

It's ok for me 😃.
Do you want to add an example in the doc?

[Sly777]

I added examples 👍 aaaaandd it's finished i guess 😄

@Sly777 Nice. I would normally ask to squash down the commit, but since it's your first contribution, let's skip it.

wouldn't be better if we set labelMember = displayMember if it wasn't passed instead of set it to 'text'?
I'd say in most of the cases we want the same property to be displayed in both places..
Besides it'll break some apps (my case)..

That's a regression indeed! Sorry.

Sounds good.
Could you submit a PR for this? Otherwise can you open an issue and I will fix it.
Thanks for raising this issue!
