The module features a number of base forms in this hierarchy: * AbstractLookup * AbstractLookupMulti * svyLookupTableMulti * svyLookupNGTableMulti * svyLookupTable * svyLookupNGTable You can extend the Abstract forms for a fully custom implementation of the UI, while you can extend any of the svy\* to customize the given template form. Extend any of the \*Multi form is suitable to implement lookup template for multi selection, while other templates are suitable for single selection. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.servoy.com/guides/develop/programming-guide/extensions/modules/svylookup/custom-templates.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
