You can select list fields in the upper left window of the Query Painter. The fields are displayed in a tree whose structure is derived from that of the data source. If your data source is a logical database, then the nodes of this tree are the same as the logical database nodes. With joins, each table's individual nodes make up the node of the tree. All fields are found under their corresponding node.

Two radio buttons are assigned to each field. When you select the first radio button, its field is selected and transferred to the layout window, and as a result of this to the list as well. You can also make this selection simply by double-clicking on the field name. Selecting the second radio button makes the field into an additional selection criterion.

Selected fields are highlighted in color. Depending on how many fields you select, the are either inserted one after the other in a single line or in multiple lines.

If you do not want to fill every line, but instead want to move to the next line and resume filling there, you can insert new lines using the Insert line symbol in the toolbox. Those lines you have selected are then placed in the new line inserted.

To delete selected fields, undo the field's selection, or drag the trash can icon from the appropriate toolbar to the field you want to delete. Deleted fields are stored in the trash and can be re-inserted into the list according to need. The fields attributes remain the same as when they were deleted.
