I had an earlier post about cross browser safe select replacements. This is a function which replaces the gravity forms plugin select drop downs with those cross browser safe drop downs.

//REPLACE GRAVITY SELECT DROPDOWNS
function replaceGravitySelects(){
	var optionValues = [];
	var optionHTML = [];
	var selected = [];
	var selectedHTML = [];
	var selectParent = [];
	var inputName = [];
	var tabIndex = [];
	var numSelects = 0;
	
	//get options
	jQuery('.gfield_select').each(function() {
		optionValues[numSelects] = [];
		optionHTML[numSelects] = [];
		jQuery('option', this).each(function() {
		    optionValues[numSelects].push(jQuery(this).val());
		    optionHTML[numSelects].push(jQuery(this).html());
		    
		    if(jQuery(this).is(':selected')){
		    	selected[numSelects] = jQuery(this).val();
		    	selectedHTML[numSelects] = jQuery(this).html();
		    }
		});
		
		selectParent[numSelects] = jQuery(this).parent();
		inputName[numSelects] = jQuery(this).attr('name');
		tabIndex[numSelects++] = jQuery(this).attr('tabindex');
	});
	
	for(var j = 0; j < numSelects; j++){
		var buildSelect = '<div class="dropdown subject" tabindex="'+tabIndex[j]+'"><span id="search-text">'+selectedHTML[j]+'</span>'+
							'<input id="'+inputName[j]+'" type="hidden" value="'+selected[j]+'" name="'+inputName[j]+'"></input><ul style="">';
		
		var isSelected = '';
		for (var i in optionValues[j]) {
			if(optionValues[j][i] == selected){
				isSelected = 'selected';
			}else{
				isSelected = '';
			}
			buildSelect += '<li id="'+optionValues[j][i]+'" class="'+isSelected+'">'+optionHTML[j][i]+'</li>';
		}
		
		buildSelect += '</ul></div>';
		
		// remove the old and set the new select in place
		selectParent[j].html(buildSelect);
	}
	
	// SET UP FUNCTIONALITY
	
	//MOBILE CHECK
	if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
		binding = 'touchstart';	
		
		//close the menu if it is open and the user clicks / touches ANYWHERE but the menu  
		$(document).bind(binding, function(e){
			var container = $(".dropdown.open");

    });

CSS styles. You will need to edit to fit your needs.
