# On Dropdown Value Changed

The **On Dropdown Value Changed** trigger activates whenever the selected option in a **TextMeshPro Dropdown** changes.\
This makes it perfect for creating a character customizer.

#### Inside the Trigger

**Game Object**\
A reference to the **TextMeshPro Dropdown** you want to monitor.\
When the player changes the dropdown’s value (for example, selecting a new hairstyle), this trigger will fire and execute any linked instruction

***

#### Example Use Case

You can use **On Dropdown Value Changed** to make your character customizer.\
For example:

* Attach this trigger to an **Dropdown**.
* When the player selects a new option, the trigger fires and runs a **Set Text** instruction that uses the **Set Part (String Property)** to apply the selected part to the Sidekick Character.
