# Attaching a Suggester – a component with suggestions

*Suggester* It is a special type of external data source used mainly for text fields. Its task is to suggest or automatically correct the value entered by the user, according to a specified algorithm. The suggester works on the server side – when the user enters data and leaves the field, the suggester service can, for example, modify that value (enforcing a specific format, range, etc.) or suggest another one.

**Step-by-step configuration:**

1. **Component selection:** Select the component of type **Text field** (TextField) for which the suggestion or correction mechanism is to be enabled.
2. **Selecting a suggester:** In the Properties panel, go to the Interactions section. In the field **External data source** click **Select a service**, and then select the appropriate **Suggester**. After attaching it, the suggester's identifier should appear in the field (e.g. its name).
3. **Automatic value update:** In the Other properties section of the text field, select the option **Automatic value update** (autoServerUpdate). This setting causes the value to be sent to the server after each end of editing of the field (e.g. when leaving the field or losing focus). This way, the suggester receives the value entered by the user and can return a possibly modified one. If the autoServerUpdate option is not enabled, the suggester will not work – changes to the field value will not be recorded on the server side.
4. **Finishing the configuration:** After completing the configuration, save the changes. From that moment on, the text field will be linked to the Suggester. When the user enters a value and finishes editing it (e.g. moves to the next field), the suggester mechanism will process the entered value. If it requires correction, the system will automatically replace it with the suggested one (e.g. increase it to the minimum allowed value). The Suggester can also display messages to the user – for example, information about the correction made.
5. **Customizing messages:** If the suggester has default messages (e.g. in English), it is worth translating them into Polish. To do this, go to the tab **Translations** in the application editor and find the message keys associated with the given **Suggester**. Then add the appropriate Polish translations.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.eximee.com/documentation/documentation-en/budowanie-aplikacji/interfejs-uzytkownika/formularze/praca-z-komponentami-bazowymi/zasilanie-wartosciami-z-zewnetrznych-zrodel/podpiecie-suggestera-komponent-z-podpowiedziami.md?ask=<question>&goal=<endgoal>
```

`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.
