ASP open dropdown from code behind

I have a drop down that will open using example code from. https://jsfiddle.net/fz2sY/39/. However if I call the same function from code behind. ScriptManager.RegisterStartupScript(this, this.GetType(), "","runThis(dropdown);", true);

The dropdown is inconsistant and opens sometimes but more often fails. Is there anything that can be changed in the code behind to make the function call more reliable?

You need to call ShowDropdown function after window load 

ScriptManager.RegisterStartupScript(this, this.GetType(), "","window.onload = function(){ showDropdown(document.getElementById('dropdown'));}", true);
