== Description of the Function ==
The '''Drop-down''' function is most commonly used in the application within individual form fields for selecting from a predefined list of values. You can recognize it by the arrow on the right side of the field. Clicking on the arrow will expand the list of values in alphabetical order.

An example of this is the '''City''' field in the transportation chain. You can enter any text into it, which is then used to search and filter individual values in the list. To start autocompleting, you need to enter '''at least 2 characters.''' Additionally, you can search '''by multiple attributes at once''', for example, '''Prague CZ''' or '''Prague 10400'''. This way, you can more precisely filter the results and select only from the values you prefer.
<br>
The Drop-down can also be multiline. The application can display up to 3 rows beneath each other, and the user can then search based on the information from the second and third row.
<br>
If we fill in an exact match with the value in the drop-down, we can use the {{key press|tab}} key to immediately exit the field, and the application will automatically fill in the value in the field.

== Display of Historical/Invalid Records ==
A historical/invalid record refers to data from a directory that has been deleted or modified over time. 


There are three types of record historization.

A deleted or invalidated record is '''not visible''' in the drop-down menu. If you edit an older record, the invalid record (Mr.) will be visible in the field. However, when attempting to edit this field, it will no longer be in the drop-down menu (Mr. is missing).

2. A deleted or invalid record '''is visible''' in the drop-down menu, '''however, it cannot be selected and saved'''. This type of invalid data will be displayed in the drop-down menu for one year from the date of invalidation.

If an invalid data is selected, the application will alert you to this fact, and it is necessary to select a valid data.

3. A deleted or invalid data '''is visible''' in the drop-down menu '''and can be selected''' (applies for a period of 90 days from the removal of the record). If you edit an older record after the specified period has elapsed, the invalid record will be visible in the field. However, when attempting to edit this field, it will no longer be in the drop-down menu.
