To hide a column, click the minus button to the left of the column name. If a column does not have a name, click the minus button in the column header row.

To display a hidden column again, click the Hide/Show toggle button, which is located below the section name.

The Hide/Show table appears. It contains the attributes associated to the BOM, as well as three other columns included in the BOM section: the Insert, Select, and Expand columns. The Hide/Show table is most effective for hiding or showing a large number of attributes and columns at once, rather than hiding them one by one.

You can select those attributes and columns that you want to display in the current BOM section by selecting the corresponding checkboxes. Clearing the checkbox for an attribute removes that column from the BOM section, and is equivalent to clicking the minus button to the left of the column name.

You can also click Hide All or Show All to select or clear all checkboxes in the Hidden column. This is an efficient way to select all attributes associated to the BOM, as well as the Insert, Select, and Expand columns. If you click Show All, you can still manually remove select attributes or columns by clearing the corresponding checkboxes.

The section table dynamically updates as you select attributes or columns. When you have finished selecting the attributes or columns you want to view for the BOM section, click Hide/Show to hide the Hide/Show table.
