+The [[jvx:client:gui:custom_linked_celleditor|linked cell editor]] is a combobox with a table in it. The table has one or more columns, and it's possible to choose one value from the table as display value. Here's an example:

-The combobox is a very special control because not all GUI technologies show more than one column in a combobox. In desktop technologies like Swing, it's not a problem to show more than one column. In web technologies it's unusual to show more than one column. Usually, only one column (= display value) will be used in a combobox. Here's an example:

+If you want to show multiple columns in such GUI technologies, you have to use a calculated column which concats the values of different columns to one column. With JVx, this can be done very easily. Simply write one line of code:
+  ((ILinkedCellEditor)book.getRowDefinition().getColumnDefinition("SALU").getDataType().getCellEditor()).setDisplayConcatMask("* (*)");
+The example sets a concatenation mask (* (*)) for the cell editor (ILinkedCellEditor) of a specific column (= SALU). The concat mask supports wildcards (= *). Every * is a column from the ColumnView. The order is defined by the ColumnView column order. It's also possible to set a simple concat mask without wildcards:
+  ((ILinkedCellEditor)book.getRowDefinition().getColumnDefinition("SALU").getDataType().getCellEditor()).setDisplayConcatMask(" ");
+In this case, a space will be used to separate all columns. Here's an example with a wildcard concat mask:
+{{:jvx:client:gui:linkedcelleditor_html5_concat.png?300|}}
+It's a good idea to use the concat mask only in web environments. This can be configured with the following code:
+  if (getApplication().getLauncher().isWebEnvironment())
+  {
+    //set the concat mask
+  }
