Thanks @intregal . I did the above implementation as u suggested, it didnt increase the width. But whatever logic i tired the width is not getting increased for both multi-combo box and side menu width. Below is the logging for the width of both of them… this width remains the same
//console.log(this.getPopup());
o {$ready: Array(2), i: {…}, j: {…}, k: {…}, VE: {…}, …}
$customWidth:ƒ (t)
$d:undefined
$height:215
$ready:(2) [ƒ, ƒ]
$scope:null
$view:div.webix_view.webix_window.webix_popup
$width:316
VE:{obj: o}
//console.log(topParent);
o {$ready: Array(0), i: {…}, j: {…}, k: {…}, VE: {…}, …}
$d:undefined
$height:779
$ready:[]
$scope:null
$view:div.webix_view.webix_window.webix_popup.webix_sidemenu.webix_sidemenu_left
$width:300
