A JCR configured select field does not work with filtering. I attach my select field configuration as bootstrap file config.modules.pages.dialogs.editPage.form.tabs.tabPage.fields.select.xml.

Steps to reproduce

1. Go to https://demoauthor.magnolia-cms.com/.magnolia/admincentral#app:configuration:browser;/modules/pages/dialogs/editPage/form/tabs/tabPage/fields:treeview:
2. Add a select field with filtering, described here https://documentation.magnolia-cms.com/display/DOCS/Select+field
3. Open https://demoauthor.magnolia-cms.com/.magnolia/admincentral#app:pages:;/sportstation:treeview: and click "Rename page"
   1. In the select field you can type, but nothings happens, no filtering (see screenshot-1.png)

Solution

1. Introduce new setter SelectFieldDefinition#setFilteringMode(FilteringMode)
2. Provide documentation for SelectFieldDefinition#filteringMode and SelectFieldDefinition#getFilteringMode
