React Filter Builder - Customization

In this demo, a custom filter operation, "anyof", is implemented. The calculateFilterExpression function converts it into DataSource-compatible operations. The compatible and incompatible filter expressions are displayed under the FilterBuilder.

The set of available group operations is limited to "and" and "or" using the groupOperations array, and the groups’ maximum nesting level is limited to one using the maxGroupLevel.

To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.
