Selectors and Filters

Throughout the Nectar Dashboard you’ll find our Nectar selectors and filters to help you search for and select images, flavors, security groups, networks etc. You can build specifically structured filters, or type free text into them. Find out below how you can make them work best for you.

Let's start with an example of the selectors and filters. The screenshot below is of the Launch dialog, on the Flavor tab. The red highlighted box will show the selected option. The grey highlighted box shows the available options. The arrows show respectively the Filter area (left) and the Selector button (right, one for each available option).

Selecting

To select one of the available options, simply click its selector button. Your choice will now be transported to the area for the selected option. To unselect the selected option, you can either click the unselector button (the downward pointing variant of the selector button) or simply overwrite the selected option, by selecting a different choice from the available options. The example below shows how clicking the selector of the flavor m2.medium shows it in the selected option area. Options for unselecting are illustrated on the right. 

Filtering

In case the list of available options is long (e.g. for the list of images in Nectar) you can apply filtering. You can either use the free-text filtering or you can build a specific filter. In the first screenshot below of the Source tab in the Launch Dialog, you can see how free text filtering for the term "scientific linux" (red highlighted box) shows all Nectar's images that fit the keyword search (in the grey highlighted box). 

This example screenshot below illustrates how to build a filter for images. First click in the filter area. A small list of filter-enabled attributes will appear. Click to select an attribute. This example shows the Visibility attribute of images. Upon selecting an attribute, a list of options will appear, for your attribute. In this example Public, Private, Shared with Project and Community. Select a value to complete this filter. You can create multiple filter elements via this method, just repeat the steps. 

Some attributes may not have a predefined list of value options. Those attributes will allow you to enter free text in the second step.
