When I have a collapsible panel, ExtJs renders an icon in the tools area to expand/collapse, but also puts a little black triangle between the panels to do exactly the same thing.
I found in the documentation that I can hide the icon in the tools area, using hideCollapseTool:true, but I want to hide that little black triangle instead. How to do that?
In Ext JS 5 (and likely some earlier versions as well) the split configuration parameter can be either a boolean value or a configuration object for an Ext.resizer.BorderSplitter object.
According to the API the collapsible property can be used to manually show or hide the collapse button in the splitter, so you can set that property to false to hide that button you're talking about.
The solution tested and working in 5.1 looks like this, assuming the panel is contained in a container with a border layout:
{
xtype: 'panel',
region: 'west',
split: {
collapsible: false
}
}
P.S. I know this is 2 years late but I found this question while looking for the solution myself. Figured I might as well share the solution from the API.
Edit: Made a fiddle. Also, it's worth mentioning that this retains all of the other splitter functionality that is lost if you use split: false, such as keeping the panel resizable.
