Updates the Data Widgets module documentation to match the current widgets (Data Widgets 3.x, Data Grid 2 3.11). Property names, defaults, and visibility conditions were checked against the widget XML and editor configuration in mendix/web-widgets.

Changes

Data Grid 2

• Data Grid 2 – Properties: reorganized by Studio Pro tab and documented all current properties, including their defaults and when each property is shown.
• Show number of rows: describes the "20 of 150" counter and notes the initial-load cost on large datasets.
• Filters placeholder: also holds other widgets, such as action buttons. The note on grid-wide filtering being removed in 3.0.0 is now an alert instead of a heading.
• Data Grid 2:
  • Aligned the Auto/Custom explanation and the On change event descriptions for the text, number, date, and drop-down filters.
  • Renamed "header" to "filters placeholder" in the selection and action button sections and in troubleshooting.
• Removed outdated content: the Performance section (Data Widgets 1.x) and the Atlas v2 troubleshooting.

Filter widgets (text, number, date, drop-down)

• Aligned property names, defaults, and visibility rules with the widgets.
• Saved attribute: explains that the saved value is not applied automatically and must be used in the Default value expression. This applies to the text, number, and date filters.
• Number filter: clarified Filter attributes (Auto works only in a Data Grid 2 column; use Custom in a filters placeholder), and made property descriptions start with a verb, like the other filter pages.
• Drop-down filter: uses "Drop-Down Filter" and "drop-down" consistently, following the terminology guide.

Gallery

• Updated pagination, selection, and filtering sections. Removed the Advanced Options section, which no longer exists in the widget.
• Added a note that the pagination status text and screen reader labels of the paging buttons are not yet translatable.
• Clarified that the Selection Helper only selects and deselects items on the current page.
• Removed first-person wording and four images that are no longer used.

Selection Helper

• Clarified that the helper acts on the current page only. Items selected on other pages stay selected when Keep selection is set to Yes.
• Uses "filters placeholder" instead of "header".

Tree Node

• Named the Infinite tree node mode consistently and explained that it is used when Parent association is set.
• Clarified that Has children is hidden in that mode.

Data Widgets module

• Updated the widget list and link names.

Verification

• Behavior that the old docs described incorrectly (Selection Helper scope, drop-down filter saved attribute) was checked in a test app with Data Widgets 3.11.7.
• No anchors that other pages link to were removed.
