You can add a style attribute to the input javascript like so:

this.input = $( "<input>" )

.appendTo( this.wrapper )

.val( value )

.attr( "title", "" )

.attr( "style", "width: 600px;" )

.addClass( "custom-combobox-input ui-widget ui-widget-content ui-state-default ui-corner-left" )

.autocomplete({

delay: 0,

minLength: 0,

source: $.proxy( this, "_source" )

})

.tooltip({

classes: {

"ui-tooltip": "ui-state-highlight"

}

});
