AND Condition

The “AND Condition” filter rule is a container that can hold multiple sub-filter rules. All contained filter rules are combined with an AND link: an item must fulfill all sub-conditions to appear in the result set.

Since filter rules at the same level within a filter set are automatically linked by AND anyway, the AND condition is primarily needed for structural organization within an OR condition. This allows complex filter combinations such as (A AND B) OR (C AND D) to be built.

This filter rule has no frontend widget output.

Installation

This filter rule is part of metamodels/core and is available without additional packages after the basic MetaModels installation.

Matching Attributes

The AND condition is not an attribute-bound filter, but a structural container. The contained sub-filter rules can use any attributes.

Special Functions

Hierarchical filter structure

Via the clipboard icons in the filter rule list, a filter rule can be inserted into an AND condition (or OR condition). This creates a nested filter structure that can map nearly arbitrarily complex logical expressions.
