# Frequently asked questions (FAQ)

### Where do I create new fields?

Under **Catalogues > Article Configurator > Own/Additional Fields**. There you create fields and assign them to products, categories or dynamic product groups.

### Why does my field not appear in the frontend?

Check the following points:

* Is the field assigned to a **product**, a **category** or a **dynamic product group** that the product belongs to?
* Does the **priority rule** apply? A direct product assignment overrides category and dynamic product group assignments (see [Field assignment & priorities](/artikel-konfigurator/english-documentation/feldzuordnung.md)).
* Is the field controlled by a [dependency](/artikel-konfigurator/english-documentation/abhaengigkeiten.md)? Then it only appears after the checkbox has been confirmed.
* Has the **cache** been cleared and the **storefront** rebuilt if necessary?

### How do I enable surcharges?

Enable the option **Enable prices for option fields** in the [plugin configuration](/artikel-konfigurator/english-documentation/plugin-konfiguration.md). After that you can store **name + value** per option for dropdown, single and multi select.

### What is the difference between a surcharge and a multiplier?

A **surcharge** is added as a fixed amount to the product price. A **multiplier** multiplies the stored value of the option by the selling price – the surcharge therefore depends on the price of the product. More on this under [Surcharges & multiplier](/artikel-konfigurator/english-documentation/preise-und-multiplikator.md).

### How do I restrict the permitted file formats on upload?

Enable the option **Restrict file formats** in the [plugin configuration](/artikel-konfigurator/english-documentation/plugin-konfiguration.md) in the **Field type: Media upload** section. After that you can select the **allowed file formats** in the respective upload field.

### How do the entries appear on the delivery note?

Enable the option **Show in order documents** in the field. The entries are then output per order line item on the document (see [Output in order & documents](/artikel-konfigurator/english-documentation/ausgabe-bestellung-belege.md)).

### Can I maintain fields in several languages?

Yes. Name, placeholder, info text and available options are stored per language. Use the **language switcher** at the top right of the field's detail view.

### Can fields be defined as required?

Yes. Enable the **required** option in the field settings. The field must then be filled in before adding to the cart. With [dependencies](/artikel-konfigurator/english-documentation/abhaengigkeiten.md), the requirement only takes effect after the checkbox has been confirmed.

### Can fields apply to many products at once?

Yes. Assign the field to a **category** or a **dynamic product group**. Via the [plugin configuration](/artikel-konfigurator/english-documentation/plugin-konfiguration.md) you can additionally include child and parent categories.
