Reloading the toolbox

Function

The "Reload Toolbox" icon or button reloads all the components in the toolbox. After reloading:

• The list of controls and section templates in the toolbox updates.

• ​Section templates used in your form also update to their latest published version.

Orbeon Forms 2017.2 and newer

The "Reload Toolbox" button is located at the top of the "Advanced" tab.

Orbeon Forms 2017.1 and earlier

The "Reload Toolbox" icon is located at the top of the toolbox:

Form structure

New Section button

Pressing this button inserts a new section into the form. The section is inserted after the currently selected section, that is the section containing the currently selected control.

After insertion, the new section has an empty title. You can change the section title by clicking on it.

New Grid button

Pressing this button inserts a new grid into the form. The grid is inserted after the currently selected grid within the currently selected section, that is the section and grid containing the currently selected control.

New Repeated Grid button

Pressing this button inserts a new repeated grid into the form. The grid is inserted after the currently selected grid within the currently selected section, that is the section and grid containing the currently selected control.

After insertion, the new grid has one column and one cell. You can change the dimensions of the grid using the grid icons. You can change the grid settings with the Grid Settings icon.

Form controls

The toolbox contains the user interface controls you can insert into your form, grouped by category:

To add a control to your form, simply click on the control. The following insertion logic is implemented:

• If the currently selected grid cell is empty, the control is inserted there.

• Otherwise, if the cell to the right of the currently selected grid cell is empty, the control is inserted there.

• Otherwise, if the control is the last control of the grid, a new grid row is inserted and the control is inserted in the first cell of the new row.

• Otherwise, the controls in the toolbox are disabled and you cannot insert a new control.

Data dropdown

From the perspective of people who will be filling out your form, the data dropdown works just like a regular dropdown. However, the data in the dropdown comes from a service. For instance, imagine you have a list to select a state and that you don't want to hard code the list of states in the form, either for convenience, or because the subset of selectable states is dynamic:

1. Insert a data dropdown field.

2. Click on cogwheel to bring up a Control Settings dialog, similar to the one shown to the right.

3. In the Resource URI, enter the address of an HTTP service that returns the data you want to use to populate the dropdown. In most cases, the URL will look like http://your-host/your-service. If the address you specify start with a /, it is relative to the Orbeon Forms web app, which allows you to access a service you might have implemented in Orbeon Forms with XPL. For this example, let's assuming your service returns a list of states that looks like:

<states>
    <state abbreviation="AK" name="Alaska"/>
    <state abbreviation="AL" name="Alabama"/>
    <state abbreviation="AR" name="Arkansas"/>
    ...
</states>

1. In the Items field, enter an XPath expression that returns one node per state. In this case, it will be: /states/state.

2. For each state (item), specify an expression relative to the node returning the label (shown to users in the dropdown) and the value (stored in the data). In this case, those expressions will be, respectively: @name and @abbreviation.

If the data in the dropdown depends on a value entered by users in another form field, you can pass that value to the service as a request parameter. For instance, let's say that in addition to the State dropdown, you have a City dropdown where you want to list all the cities in the currently selected state. If the service is at /xforms-sandbox/service/zip-cities and takes a request parameter state-abbreviation, assuming you named your State field state, in the Resource URI enter:

/xforms-sandbox/service/zip-cities?state-abbreviation={$state}

Limitation: you can't yet use a variable as shown in the above example, to refer to another fields value. Instead, if the control is in the same section use {../state}. If in a different section with name other-section, use {../../other-section/state}. See #431.

Autocomplete

The autocomplete control is a single item selection control that loads a list of suggestions from a service. It takes the same Resource URI, Items, Label, and Value configuration parameters as the [Data dropdown control][46]. You may want to pass the value of other controls to the service, but you'll always want to pass the currently typed value, as the suggestions should depend on what users typed so far. You access to the currently typed by value with $fr-search-value, as in the following example:

/xforms-controls/services/countries?country-name={`encode-for-uri($fr-search-value)}
