jQuery popup min and max width/height

If I set the popup minWidth to 440 px (example), will the width automatically grow with the content? Do I have to write extra code to make it dynamically growing?

dialogDiv.dialog({
        title: "Confirm Delete",
        autoOpen: false,
        modal: true,
        draggable: false,
        resizable: false,
        closeOnEscape: false,
        minWidth: 440,
        minHeight:220,
