 For elements of catalogs operation SORT is available, which activates by link in upper-right part of content-view area. Then on the screen appears window with list of features with round-boxes, in which you can choose direction of sorting (ascending or descending) of each feature. Direction of ascending sorting indicates as triangle directed upwards, descending sorting as down-directed triangle.
Hierarchical sorting can be realized only with 3 levels maximum. That means, if needed to sort elements of catalog firstly by type of stone and then foer each type of stone by name, then you should firstly determine sort for feature STONE TYPE and then set sorting for feature NAME. In this case in right part of the window will be shown values selected for sorting and sort order. To begin sorting you should use "OK" button in lower part of the window. For canceling all checks you should use "RESET" button situated near "OK" button in lower part of filter window. To close sorting window without executing operation, click on the name of window (SORT) in upper part of the window or click anywhere outside the window.
Additional info about functional possibilities and use of them available on corresponding sites of chapter HELP.
