Cannot drag and drop elements in the WYSIWYG design editor

WYSIWYG design editor in WebAsyst Shop-Script allows moving web page elements by means of the drag-and-drop technique. Design elements that can be dragged and dropped are outlined with red dotted lines:

If usually movable objects cannot be moved any more, check the validity of the HTML code of your design. If it contains non-closed tags or other serious mistakes, several functions of the WYSIWYG design editor (including the drag-and-drop) may not work.

Should you face problems finding mistakes in the HTML code, try to reset the currently used template by clicking on the "Reset theme (discard all changes)" link. After that repeat the design modification process set by step and the functionality of the WYSIWYG editor after each change applied. This approach will allow to find out what design change disrupts normal operation of the editor.
