TabControl demo
This is a demo that shows how a tab-control can be used.
A tab-control can be used for editing a collection of data elements. Each element will be presented by a tab. Using the navigation buttons you can navigate through the tabs, and using the "+" and "-" buttons you can respectively add new data elements or remove data elements from the collection. Within a tab a form is displayed where you can edit the fields of the currently selected data element. Note that the form of a tab is modeled in a logicnet, hence you can model any kind of logic to determine what inputs to show on the tab dependent on the data.
In this example we are creating a tab control that manages a collection of persons.

| --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://community-test.logicnets.com/release-9/platform-documentation/advanced-topics/external-document-storage/document-definitions/data-section.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
