Hello,
I want to show tooltip on only task area, not grid.
How it’s possible?

Hello,
You need to change onMouseMove event in tooltip extension file tooltip.js to the next:

t.attachEvent("onMouseMove", function(e, i) {      
      if (i.clientX > gantt.config.grid_width) {        
        if (this.config.tooltip_timeout) {
            document.createEventObject && !document.createEvent && (i = document.createEventObject(i));
            var n = this.config.tooltip_timeout;
            this._tooltip_id && !e && (isNaN(this.config.tooltip_hide_timeout) || (n = this.config.tooltip_hide_timeout)),
                clearTimeout(t._tooltip_ev_timer), t._tooltip_ev_timer = setTimeout(function() {
                    t._init_tooltip(e, i)
                }, n)
        } else t._init_tooltip(e, i)          
      }                     
    })
