Hello,

You can try to redefine the internal method that closes layout cell as follows (here "a" is id of non-closable cell):

var dhxLayout = new dhtmlXLayoutObject(...);
dhxLayout._collapse_old = dhxLayout._collapse;
dhxLayout._collapse = function(pId, mode) {
  if(pId == "a") return;
  dhxLayout._collapse_old(pId,mode);
}

Hello,

This works great, just one more point, is there any way to hide the arrows for the particular pane that has been disabled in this way?

Many thanks

Scott

Hello,

Layout API doesn't allow to do that. But you can modify the dhtmlxlayout.js as follows:

locate _fixIcons method and add if(a == "cell id") continue; for the necessary cell:

this._fixIcons = function() {
  for (var a in this.polyObj) {
  if(a == "a") continue;

...

}
