See https://rpg.hamsterrepublic.com/ohrrpgce/Slices for further description of each type.

Container - An invisible slice used for positioning other slices.

Rectangle - A box which can be give a color and a border-style

Line - A straight line drawn between two opposite corners of the slice.

Sprite - A sprite. Draw sprites in the graphics menu (go back to the main menu to find it)

Text - A string of text. Can optionally wrap as multiple lines.

Grid - A special container with rows and columns. Children of the grid are automatically positioned relative to the grid cells.

Ellipse - An ellipse which can have a fill-color and a border-color

Scroll - A special container that draws scrollbars if its child slices are too big to fit inside it

Select - A special container that manages the visibility of its children. Only one selected child will be visible, and all other children will be hidden

Panel - A special container that only allows 2 children (extra ones are ignored). The panel space will be divided between the two children according to a percentage or a fixed number of pixels, or can place the slices beside each other, like Layouts.

Layout - A special container which positions its children end-to-end and wrapped onto multiple rows or columns, like words on a page or elements in an HTML document. A good alternative to a Grid if the children are different sizes.
