Accordion multi parameter

i am using the multi parameter in an Accordion like this multi:“mixed”
but it doesn’t work i am still able to collapse all tabs.

Please share a demo link or a snippet where issue can be checked.

if you just add a resizer between the columns you will see the problem
Ex: webix.ui({
multi:“mixed”,
view:“accordion”,
height:600,
width:700,
cols:[
{ header:“col 1”, body:“content 1”},{view: “resizer”},
{
collapsed:false,
header:“col 3”,
body:“content 3”,

				},{view: "resizer"},
				{ header:"col 5", body:"content 5"}
			]
		});

Techically, this behavior is correct

Accordion in mixed mode allows to collapse cells while at least one view is not collapsed, in your case the resizer view is not collapsed, so it allows to collapse all others.

And yes, I’m agree that current behavior is not practical and need to be fixed.
