A drop-down list or drop-down menu or drop menu, with generic entries. A drop-down list (DDL), drop-down menu or just drop-down [1] – also known as a drop menu, pull-down list, picklist – is a graphical control element, similar to a list box, that allows the user to choose one value from a list either by clicking or hovering over the menu.
The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects. DOM methods allow programmatic access to the tree; with them one can change the structure, style or content of a document. [2] Nodes can have event handlers (also known as event listeners) attached to them. Once an event is ...
A common example using a GUI accordion is the Show/Hide operation of a box region, but extended to have multiple sections in a list. SlideVerse is an accordion interface providing access to web content.
Selenium Grid is a server that allows tests to use web browser instances running on remote machines. With Selenium Grid, one server acts as the central hub. Tests contact the hub to obtain access to browser instances. The hub has a list of servers that provide access to browser instances (WebDriver nodes), and lets tests use these instances.
It has been noted [5] that the plural "files" in the above quote is an indication that, in HTML 4.01, a single-file select-control still was supposed to handle selection of multiple files and not just a single file. This situation is being clarified in HTML5 by adding a "multiple" attribute when the file input should accept multiple files.
A specification, as previously explained, is the product of a software development process phase that receives another specification as input. A specification is verified successfully when it correctly implements its input specification. All the specifications can be verified except the SRS because it is the first one (it can be validated, though).
Ionized selenium (Se+24, where 24 of the outer D, S and P orbitals are stripped away due to high input energies [clarification needed]) is one of the active mediums used in X-ray lasers. [ 92 ] 75 Se is used as a gamma source in industrial radiography.
In one unusual design, small selenium diode discs were used with germanium transistors. The recovery time of the very slow selenium diodes caused a glitch on the inverter output. It was fixed by placing a selenium diode across the base-emitter junction of the transistor making it think it was a selenium transistor (if there could ever be one).
