DataMap Editors (React)

By default, the FlexGrid provides a drop-down list for editing data-mapped cells.

In the V1/2020 release, we added a dataMapEditor property to the Column class. This new property allows you to select the type of editor you'd like to use on your data-mapped columns. You have three options:

DropDownList: Use an input element with auto-complete, validation, and a drop-down list. (This is the default setting.)

AutoComplete: Use an input element with auto-complete and validation, but no drop-down.

RadioButtons: Use radio buttons with mouse and keyboard support. This option takes up more space, but it's the only one that shows all available choices at once and provides single-click editing.

Menu: Use an Input element that displays a text element with a drop-down list of commands that the user can invoke by click or touch. Does not support editing values
