Custom fields let you capture and store information that goes beyond the standard contact and record details in Aesthetix CRM. The field _type_ you choose controls how data is entered, validated, and displayed, so picking the right type up front keeps your data clean and your forms easy to use.

This reference covers every custom field type available in Aesthetix CRM, what each one is best used for, how to create it, and the type-specific options you'll see along the way. Every type is created from the same place, **Settings > Custom Fields**, using the **Add Field** button. For the full create, edit, and delete workflow, including how fields are grouped and managed over time, see the [**Creating and Managing Custom Fields**](https://help.aesthetixcrm.com/en/articles/1476-creating-and-managing-custom-fields.md) guide.

> **Note:** No matter which type you choose, the core flow is the same: open **Settings > Custom Fields**, click **Add Field**, select the type, review the preview, click **Next**, then configure the field's name, group, object, options, and description before saving.

## Tips & FAQ

**Which field type should I choose for a short text answer?** Use **Single Line** for brief responses like a name or address, and **Multi Line** when users may write longer comments, descriptions, or feedback.

**What's the difference between a Single Dropdown, Radio Select, and Checkbox?** A **Single Dropdown** and a **Radio Select** both let users pick exactly one option, but a dropdown hides choices in a menu while a radio select shows them all at once (and supports per-option icons). A **Checkbox** lets users select multiple options at once.

**When should I use a Multiple Dropdown instead of Checkboxes?** Both allow multiple selections. A **Multiple Dropdown** keeps a long list compact inside a menu, while **Checkboxes** display every option on screen, which works best for shorter lists where you want all choices visible.

**What is the "object" drop-down on each field?** The object selection determines which record type the custom field is attached to. Choose the object that matches where you want the field to appear.

**Do I need to set a unique key?** Only if you want to control the field's internal key, often for forms, surveys, or integrations. Otherwise the key is generated for you. You'll find it under **Additional Preferences**.

**What are placeholder and prefill values?** A placeholder is the hint text shown inside an empty field. A prefill value automatically populates the field with a default entry, which is handy on forms and surveys.

**How do I edit or delete a custom field after creating it?** All custom fields are managed from **Settings > Custom Fields**. See the **Creating and Managing Custom Fields** guide for the complete create, edit, group, and delete workflow.
