The Combobox lets users pick one or several options on a flow screen, from a typed list, a collection, a picklist field or a query. These tutorials follow a support agent logging a case: picking the account, the reason and its detail, then using those choices further down the flow. {% hint style="info" %} New to the component? Start with [Build Combobox Options](/flow/tutorials/components/combobox/build-combobox-options.md), then keep the [Combobox reference](/flow/flow-components/combobox.md) open for every property. {% endhint %} ## Set up the options Decide where the options come from, and help users find the right one in a long list.

To build options in a flow before the screen, see the [Text Collection to Combobox Options](/flow/actions/data-conversion-and-formatting/text-collection-to-combobox-options.md) and [New Combobox Option Collection](/flow/actions/ui-and-navigation/new-combobox-option-collection.md) actions. --- # 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://docs.avonnicomponents.com/flow/tutorials/components/combobox.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.
