For a Column, how to show the label of the object but keep the ID somewhere of each label

[darkomenx]

Hi PlutoGrid and everybody,

Can you tell/help me to understand how can I show a value into column BUT keep the ID information of that value.
I need the ID information of the objects selected into column for persist/create data into a relational database.

Example :

Category
shop
car
home

But when I get value of the rows, I need to get the IDs of the objects category and not the label.

How can I do that ?

I hope to be clear otherwise tell me and thank you for your help.

I resolve my question like that :

1. create Map<String, String>
2. create List of keys from Map
3. assign my List of keys into the PlutoColumnType.select
4. when _onChange() is trigged on this field I search value into Map with keys selected in list

to customize according with your requirement
