**Motivation**
As a user I want to be able to edit existing data entries of the termbox. This will increase data quality and the multilinguality of Wikidata.
**Workflow**
Given I'm on a page showing the termbox component in an editable state, when clicking the edit button (pen icon) then the termbox entries (labels, descriptions and alias(es)) of all shown languages will switch to edit mode.
Shown languages cover all languages visible, so if languages are hidden but later will be shown (e.g. by expanding the termbox fully) these language entries will be in edit mode as well.
Edit mode means that all labels, descriptions and alias(es) will show their values in form fields. All entries will be shown in full length (no cut offs). This includes text wrapping if needed.
**Entry fields**
* Style
** 1px underline marks an entry field
*** #808080
** active entry field has a 1px blue underline
*** #3366cc
*** blue blinking cursor
** the spacing between the entry fields changes according to the mocks to 48px
* Label field
** show editability by inserting an underline
** if entry available: remain entry
** if no entry available show "enter a label"
** restrict character input to !![insert number]!!
* Description field
** show editability by inserting an underline
** if entry available: remain entry
** if no entry available show "enter a description"
** restrict character input to !![insert number]!!?
* Alias field
** show editability by inserting an underline
** if entry available: remain entry
** if no entry available show "enter an alias | seperate aliases by using a "|" " (temporary solution)
** do not restrict character input
**Buttons**
* edit button (pen)
** will not be shown after clicking
* save button (checkmark)
** show a save (checkmark) button replacing the edit button
** clicking the save button will bring the user back to reading mode having saved the entity
** button color
*** default: #3366cc
*** hover: #447ff5 (not relevant for touch, but for people using mobile on desktop)
*** active: #2a4b8d
**Mocks**
{F28203334} {F28203336} {F28203341}
{F28203345}
{F28203344}
