Gridview: customize header column display

[tinnt]

Hello all,

I have a grid which have > 50 columns, there are many column have property menuDisable:true to disable header menu and some column have menuDisable:false to show header menu. My grid work well, but not good for Look And Feel, because of the many columns I have, so that I must use mouse to check what column have header menu.
I read the source code and i see that

 this.mainHd.on("mouseover", this.handleHdOver, this);

 // private
    handleHdOver : function(e, t){
        var hd = this.findHeaderCell(t);
        if(hd && !this.headersDisabled){
            this.activeHd = hd;
            this.activeHdIndex = this.getCellIndex(hd);
            var fly = this.fly(hd);
            this.activeHdRegion = fly.getRegion();
            if(!this.cm.isMenuDisabled(this.activeHdIndex)){
                fly.addClass("x-grid3-hd-over");
                this.activeHdBtn = fly.child('.x-grid3-hd-btn');
                if(this.activeHdBtn){
                    this.activeHdBtn.dom.style.height = (hd.firstChild.offsetHeight-1)+'px';
                }
            }
        }
    },

Unfortunately my JS skill is not enough for understand. and I cannot customize it.

I try with my code: but it not work well with FF. IE show the arrow header menu, but FF not show arrow header.

function subset_column_highlight(){
    colCount = grid.view.cm.getColumnCount();
    var fields_search = new Array('vendor-item-id', 'vendor-name', 'vendor-item-desc', 'mfr-item-id', 'mfr-name', 'mfr-item-desc', 'org-item-desc', 'org-item-id');
	for (i=0; i<colCount; i++){
        if (fields_search.indexOf(grid.view.cm.config[i].dataIndex) == -1){
            //nothing
        }
        else{
            if (grid.view.getHeaderCell(i).className.indexOf("x-grid3-hd-menu-open") ==-1){
                grid.view.getHeaderCell(i).className=grid.view.getHeaderCell(i).className+" x-grid3-hd-menu-open";
            }
        }

    }

}

And I get a result as the picture below ( IE - FF )

Can someone show me another way easier ,,, thank you very much, sorry for my bad English

Regard.

Hi,

I have the same problem.
How can I always set the arrow header menu to be displayed, not just on mouseover.

Maybe somebody know it, thx
