Form options
============

For each type of form an item has an attribute that controls the modal form 
behavior:

* :doc:`view_options </refs/client/item/at_view_options>`

* :doc:`edit_options </refs/client/item/at_edit_options>`

* :doc:`filter_options </refs/client/item/at_filter_options>`

* :doc:`param_options </refs/client/report/at_param_options>`

This is an object that has the following attributes, specifing parameters of the 
modal form:

* ``width`` - the width of the modal form, the default value is 560 px,
* ``title`` - the title of the modal form, the default value is the value of a
  :doc:`item_caption </refs/client/abstr_item/at_item_caption>`
  attribute,
* ``close_button`` - if true, the close button will be created in the upper-right 
  corner of the form, the default value is true,
* ``close_caption`` - if true and close_button is true, will display 'Close - [Esc]'
  near the button
* ``close_on_escape`` - if true, pressing on the Escape key will trigger the 
  corresponding close_form  method.
* ``close_focusout`` - if true, the corresponding close_form method will be called 
  when a form loses focus
* ``template_class`` - if specified, the div with this class will be searched in 
  the task 
  :doc:`templates </refs/client/task/at_templates>` 
  attribute and used as a form html template when creating a form
  
The 
:doc:`edit_options </refs/client/item/at_edit_options>` 
has a ``fields`` attribute, that specify a list of field names that the
:doc:`create_inputs </refs/client/item/m_create_inputs>`
method will use, if ``fields`` attribute of its ``options`` parameter is not 
specified, the default value is a list of field names set in the 
:doc:`Edit Form Dialog </admin/items/edit_form_dialog>`
in the Application builder. 

The 
:doc:`view_options </refs/client/item/at_view_options>` 
has a ``fields`` attribute, that specify a list of field names that the
:doc:`create_table </refs/client/item/m_create_table>`
method will use, if ``fields`` attribute of its ``options`` parameter is not 
specified, the default value is a list of field names set in the 
:doc:`View Form Dialog </admin/items/view_form_dialog>`
in the Application builder. 

The width of the modal form, created in the following example, will be 700 px.

.. code-block:: js

    function on_edit_form_created(item) {
        item.edit_options.width = 700;
    }
