Oracle Tips by Burleson 

Text Field Attributes

Like other item types in HTML DB, the text field also has attributes: 

  • Sequence:  The order in which the text field will be rendered.  If there are two text field items with the same sequence number, the order will be when they were created.  The sequence attribute is used to control the form layout.

  • Label:  Specifies the label which will be associated with the text field.  This label can be displayed in many different positions, such as Above, Right, Left, or Below the item depending on the choice.

  • Template:  This specifies the template of the label.  Choices can be No Label, Optional, Optional with Help, Required, and Required with Help.  If the template is Optional or Required, the label will be bolded.  If either with Help option is selected, the label will be underlined and it will be a link to the help text for the field.  Additionally, if the option is Required, a icon will appear before the label to indicate that the user must enter information in the field.  How the label is shown depends on the Application theme used.

  • Display in Region:  This is the region in which the button will be rendered and displayed.

  • Post Element Text:  This is additional text that can appear after the text field.  A good use for this is to display the units for a particular value.  For example, it might be useful to display pounds after a Weight field or inches after a Height field.

  • Width, Maximum Width:  The width is the number of characters that will be displayed in the field.  The maximum width is the largest number of characters that can be entered into the field.  If the maximum width is greater than the display width, the value will scroll in the field up to the maximum width.  Text fields can only be one character in height.

  • Help Text:  The help text is used in conjunction with the Template described above.  The text entered into this attribute will be displayed when a user clicks on a label that has been defined with the template of with Help.  Upon clicking the label, a popup box will appear showing the help text.  Figure 10.35 shows an example of what the popup box for height might look like:
