Description
- JVCLInfo
TJvHTComboBox is a TJvCustomHTComboBox descendant that implements an HTML-enabled combo box. TJvHTComboBox provides the ability to render HTML tags and attributes in the Items for the component, and to trigger events when an HTML anchor is clicked.
TJvHTComboBox overrides methods in the ancestor class to provide sizing of HTML content based on changes in font size.
TJvHTComboBox recognizes the following HTML tags and attributes:

| Attribute | Usage |
| HREF | Valid URL for anchor tags. |
| ALIGN | "CENTER" or "RIGHT" ("LEFT" is the default) |
| COLOR | String representation of TColor values. |
| BGCOLOR | "clRED", "clGREEN", "clBLUE", etc. |
| SIZE | Font size in points (1/72 inch). |
| IND | Indent in pixels. |
HTML Character entities are recognized in the content for the control. The following character entities are rendered as the indicated characters or symbols:
| Entity | Character or Symbol |
| < | < (Less-than character) |
| > | > (Greater-than character) |
| & | & (Ampersand character) |
| " | " (Double Quote character) |
| ® | ® (Registered symbol) |
| © | © (Copyright symbol) |
| ™ | ™ (Trademark symbol) |
