Sometimes we require to reset the items to zero or need to clear the items in the dropdown list. Here is a simple code snippet which will reset the dropdown items.

function clearDropdown(dropdown)
{
var mycombo =document.getElementById(dropdown);
mycombo.options.length = 0;
return(false);
}

And you can use this function like this

<button onclick="javascript:clearDropdown('myoptions')">Reset Options</button>

Where myoptions is the dropdown to clear.
