A checkbox ( check box , tickbox , tick box ) is a graphical widget that allows the user to make a binary choice, i.e. a choice between one of two possible mutually exclusive options. For example, the user may have to answer 'yes' (checked) or 'no' (not checked) on a simple yes/no question .
14-399: Checkboxes are shown as empty boxes when unchecked, and with a tick or cross inside (depending on the graphical user interface) when checked. A caption describing the meaning of the checkbox is normally shown adjacent to the checkbox. Inverting the state of a checkbox is done by clicking the mouse on the box, or the caption, or by using a keyboard shortcut , such as the space bar . Often,
28-498: A tree view so that files can be selected one at a time, or by folder. If only some of the files in a folder are selected, then the checkbox for that folder would be indeterminate. Clicking on this indeterminate checkbox would select all or, less commonly, none of the contained files. Continuing to click on the checkbox would alternate between checked (all sub-directories and files selected) and unchecked (no sub-directories or files selected). Some tri-state checkbox implementations allow
42-634: A push button to initiate the action to process the data. One common exception is to enable or display additional user input elements whose relevance depends on the checkbox state. In other situations toggle switch is typically used instead of a checkbox. In web forms , the HTML element < input type = "checkbox" > is used to display a checkbox. Check mark The check or check mark ( American English ), checkmark ( Philippine English ), tickmark ( Indian English ) or tick ( Australian , New Zealand and British English )
56-493: A series of checkboxes is presented, each with a binary choice between two options. The user may then select several of the choices. This is contrasted with the radio button , in which only a single option is selectable from several mutually-exclusive choices. Checkboxes may be disabled (indicated " greyed out ") to inform the user of their existence and possible use despite momentary unavailability. Some applications use checkboxes that allow an indeterminate state in addition to
70-494: A slanted v. The opposite, "correct", is marked with ⋅ / ⋅ {\displaystyle \cdot \!/\!\cdot } , a slanted vertical line emphasized with two dots (see also commercial minus sign ). In Japan, the O mark is used instead of the check mark, and the X or ✓ mark are commonly used for wrong. In the Netherlands (and former Dutch colonies) the flourish of approval (or krul )
84-406: A sound. In Finland , it is used as a symbol for a correct response (the check mark indicates an incorrect response). In Germany, the form ./. was historically an alternative to the formal glyph, since this could be conveniently typed on a typewriter. It also provides a convenient alternative means for typing on a modern keyboard, without needing to resort to Unicode input . In Japan,
98-591: Is a mark (✓, ✔, etc.) used in many countries, including the English-speaking world, to indicate the concept "yes" (e.g. "yes; this has been verified", "yes; that is the correct answer", "yes; this has been completed", or "yes; this [item or option] applies"). The x mark is also sometimes used for this purpose (most notably on election ballot papers , e.g. in the United Kingdom), but otherwise usually indicates "no", incorrectness, or failure. One of
112-520: Is a predominant affirmative symbol of convenience in the English-speaking world because of its instant and simple composition. In other language communities, there may be different conventions. It is common in Swedish schools for a ✓ to indicate that an answer is incorrect, while "R", from the Swedish rätt , i.e., "correct", is used to indicate that an answer is correct. In Finnish, ✓ stands for väärin , i.e., "wrong", due to its similarity to
126-476: Is used for approving a section or sum. In German -speaking countries, ✓ is used for “correct” or “done”, but not usually for ticking boxes, which are crossed instead. The opposite of ✓ is ƒ (short for falsch “wrong”). Unicode provides various check marks, the one called CHECK MARK is in the U+27xx Dingbats block : The heavy check mark ✔ is available in the fonts Marlett and Webdings . On
140-505: The QWERTY keyboard, it can be produced by striking lower-case a with one of these fonts in effect. Commercial minus sign The commercial minus sign is a typographical and mathematical symbol used in commercial and financial documents in some European languages, in specific contexts. In some commercial and financial documents, especially in Germany and Scandinavia ,
154-475: The earliest usages of a check mark as an indication of completion is on ancient Babylonian tablets "where small indentations were sometimes made with a stylus, usually placed at the left of a worker's name, presumably to indicate whether the listed ration has been issued." As a verb, to check (off) means to add such a mark. Printed forms, printed documents, and computer software (see checkbox ) commonly include squares in which to place check marks. The check mark

The Unicode Consortium has allocated the code point U+2052 to identify this usage uniquely, the exact form of the symbol displayed is typeface (font) dependent. The symbol is also used in the margins of letters to indicate an enclosure, where the upper point is sometimes replaced with the corresponding number. The Uralic Phonetic Alphabet uses commercial minus signs to denote borrowed forms of
182-449: The two provided by a normal checkbox. This third state is shown as a square or dash in the checkbox, and indicates that its state is neither checked nor unchecked. This is most often used when the checkbox is tied to a collection of items in mixed states. The indeterminate state cannot usually be selected by the user, and switches to a checked state when activated. For example, a checkbox presented to select files to send via FTP might use
196-540: The user to toggle among all states, including the indeterminate state, by remembering the mixed state of the items in the collection. This serves as an undo feature. Setting or clearing (" unclicking ") a checkbox changes the checkbox's state with no other side-effects. Violating this guideline by associating additional actions with the change of state frequently confuses users, because they are used to configuring data in entry controls such as text boxes, radio buttons, and checkboxes and then invoking an action control such as
