## Description

Expands when hovered by mouse revealing additional content on left side.

Was not intended to work with transparent [StyleBox](https://docs.godotengine.org/en/stable/classes/class_stylebox.html)es, but it still can.

**Note:** Its [minimum_size](./expandablebutton.md#property_minimum_size) changes depending of it state and frame of expanding animation.

<Violet>**Note:** It is planed to add more directions.</Violet>

#### [Vector2](https://docs.godotengine.org/en/stable/classes/class_vector2.html) **base_minimum_size** = ``Vector2(0, 0)``

- *void* **set_base_minimum_size**( value\: [Vector2](https://docs.godotengine.org/en/stable/classes/class_vector2.html) )
- [Vector2](https://docs.godotengine.org/en/stable/classes/class_vector2.html) **get_base_minimum_size**( )

Minimum size of the main body.

<a name="property_expansion_indentation"></a>

#### [int](https://docs.godotengine.org/en/stable/classes/class_int.html) **expansion_indentation** = ``0``

Defines additional lenght of expanded [StyleBox](https://docs.godotengine.org/en/stable/classes/class_stylebox.html).

Added lenght will always appear underneath main [StyleBox](https://docs.godotengine.org/en/stable/classes/class_stylebox.html) unless [expansion_indentation](./expandablebutton.md#property_expansion_indentation) is negative.

<a name="property_expansion_information"></a>

- [EXPANSION_INFO](./ExpandableButton.md#enum_EXPANSION_INFO) **get_expansion_info**( )

Defines which part of content is additional.
