- Added the `mouseMode` prop to control item selection behavior. - If set to 'click', item selection will happen by clicking. - If set to 'drag', item selection will happen by dragging (similar to mobile behavior).

I am still facing this issue. Is this merged? |

Hi, @krlls , thanks for the PR. I don't see the use cases for this feature right now. If you use this component in "mobile mode" (you can toggle it using chrome devtool), you can drag n drop the item to select it. This is how it was designed to behave. So IMO there is already a "drag" mode. |

Hi!
I’ve added a
mouseModeprop that allows controlling the method of item selection with a mouse. Now, you can select an item either by clicking or by dragging, depending on the set value.mouseModeprop with values 'click' and 'drag'.
