ion-fab
Fabs are container elements that contain one or more fab buttons. They should be placed in a fixed position that does not scroll with the content. Fabs should have one main fab button. Fabs can also contain one or more fab lists which contain related buttons that show when the main fab button is clicked.
Basic Usage
List Side
The side property of the fab list component controls where it appears relative to the main fab button. A single fab can have multiple fab lists as long as they all have different values for side.
Positioning
In order to place the fab in a fixed position, it should be assigned to the fixed slot of the outer content component. Use the vertical and horizontal props to control the alignment of the fab in the viewport. The edge prop will cause the fab button to overlap with the app's header or footer.
Button Sizing
Setting the size property of the main fab button to "small" will render it at a mini size. Note that this property will not have an effect when used with the inner fab buttons.

Accessibility
Labels
Since FABs are allowed to contain only icons, developers must provide an aria-label on each ion-fab-button instance. Without this label, assistive technologies will not be able to announce the purpose of each button.
