how can I do treelist expanded without collapse option

[Ariel]

i have tree list with 'expanded: true'

i want this tree to stay expand all the time and to prevent the user collapse it.

i tried: expandable: false on first column but it doesn't work.

so, what can i do?

thanks!

Hello Ariel,

You can prevent the collapse event by calling e.preventDefault() via the event arguments.
