A string that represents the placement of the component. It consists of four letters to define the position of the component in relation to the input field. The letters are defined as the following:
- First letter: The top or bottom of input field (either t or b)
- Second letter: The left or right of the input field (either l or r)
- Third letter: The top or bottom of the component (either t or b)
- Fourth letter: The left or right of the component (either l or r)
For example, the value bltl will place the component top left position on the input bottom left position.
