Select an option from a drop-down using an option locator.
Option locators provide different ways of specifying options of an HTML Select element (e.g. for selecting a specific option, or for asserting that the selected option satisfies a specification). There are several forms of Select Option Locator.
label=labelPattern
matches options based on their labels, i.e. the visible text. (This is the default.)
label=regexp:^[Oo]ther
value=valuePattern
matches options based on their values.
value=other
id=id
matches options based on their ids.
id=option1
index=index
matches an option based on its index (offset from zero).
index=2
If no option locator prefix is provided, the default behaviour is to match on label.
