# Configure placement tag fields

Placement tag fields add custom settings to individual placements. They are available when HB Manager loads the placement.

Use them to control rendering without changing your site implementation. For example, you can define a render ID, border, breakpoint, padding, or active state.

### Open placement tag fields

In HB Manager, open **Placement Tag Fields** from the management menu.

<div data-with-frame="true"><figure><img src="/files/c6ff8a4ffabcf6b1cdee06d41b0ec9523a48bb53" alt="HB Manager menu with Placement Tag Fields selected"><figcaption><p>Open Placement Tag Fields from the HB Manager menu.</p></figcaption></figure></div>

### Create a field

Create a field by combining the required configuration options. The field then becomes available on each placement.

<div data-with-frame="true"><figure><img src="/files/439feae0cc059a0922368ac8c4c83f0c6ef804d3" alt="Placement Tag Fields configuration view"><figcaption><p>Configure the field type and its available options.</p></figcaption></figure></div>

### Apply the field to a placement

After you create the field, select its value in the placement settings. HB Manager applies that value when it loads the placement.

{% hint style="warning" %}
Custom fields can require site-side JavaScript. Test each field before enabling it in production.
{% endhint %}

### Related configuration

Use [Prebid Config Tag Fields](/technical/custom-configuration/configure-prebid-config-tag-fields.md) for settings that apply beyond a single placement. Use placement tag fields for placement-specific behavior.

## 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.relevant-digital.com/technical/custom-configuration/configure-placement-tag-fields.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.
