var autos = new Ext.form.ComboBox({ xtype: 'combo', id: 'type', store : new Ext.data.Store({ proxy:new Ext.data.ScriptTagProxy({ url:'ext_qry.cfm' }), reader:new Ext.data.JsonReader({ root:'data', id:'project' }) }), mode : 'remote', displayField: 'display', // don't understand what exactly the doc says about it editable: true, applyTo:'project' Output from firebug for the target is: And I don't understand why it set autocomplete to off, what triggered that? <div id="ext-gen6" class="x-form-field-wrap x-trigger-wrap-focus" style="width: 319px;"> <input id="project" class=" x-form-text x-form-field x-form-focus" type="text" onkeyup="document.getElementById('tagline').style.display='block'" size="50" autocomplete="off"/> <img id="ext-gen7" class="x-form-trigger x-form-arrow-trigger " src="http://extjs.com/s.gif"/> </div> > http://www.extjs.com/deploy/dev/docs/?class=Ext.data.Store > > mxAjax / CFAjax docs and other useful articles: > http://www.bifrost.com.au/blog/ > > 2009/7/6 Don L <do...@yahoo.com>: > > > >>I just use the applyTo property when setting up the ComboBox. > >> > >>> > > > > Beautiful, thank you.
