AtTheLibrary — Parameters Selection Guide

Overview

The Parameters Selection view lets you choose which family parameters appear as additional columns in the main families grid. Because families can expose many parameters, you pre-select only the ones relevant to your current task to keep the grid usable.

Note: Selecting more than 10 parameters may make the families grid difficult to use due to the number of columns.

Parameters Data Grid

The grid lists every parameter found across all families in the loaded data source.

Columns

Column	Type	Editable	Description
Is Selected	Boolean (checkbox)	Yes	Tick to include this parameter as a column in the families grid
Parameter Name	Text	No	Name of the parameter
Occurence Count	Number	No	Number of families in the data source that have this parameter

Grid Behaviour

• Extended selection — multiple rows can be selected simultaneously using Shift-click or Ctrl-click.

• Bulk selection — a select-all control is available in the column header to tick or untick all rows at once.

• The Is Selected checkbox is the only editable field. All other columns are read-only.

Choosing Parameters

Tick the Is Selected checkbox for each parameter you want to appear as a column in the families grid. Untick parameters you do not need. The Occurence Count column helps you identify parameters that are present across most families versus ones that appear in only a few.

---

Apply Button

Click Apply to confirm your parameter selection and return to the families grid.

• The families grid immediately reflects the new column selection — ticked parameters appear as additional columns.

• Your parameter selection is saved automatically between sessions.

Typical Parameters Selection Workflow

1. From the main window, expand Data Admin and click Filter Available Parameters.

2. Review the parameter list. Use Occurence Count to identify the most widely shared parameters.

3. Tick Is Selected for each parameter you want to display (aim for 10 or fewer).

4. Click Apply to return to the families grid with the updated columns.
