Exclude Visual Element From Direct Access

[danny]

So I really like this tool, but I thought it'd be cool to be able to position elements on the canvas but not have them as slides - i.e. you only view them when zooming/moving etc. I implemented this functionality by including a new attribute: data-exclude="true" (defaults to false if not present so it doesn't break existing code).

<div id="its" class="step" **data-exclude="true"** data-x="850" data-y="0" data-rotate="90" data-scale="5">

And I filter the steps right before the select method is set, insert @ line 180:

var tempSteps = [];
for (var i = 0; i < steps.length; i++)
{
  if(!steps[i].dataset['exclude'] && true)
    tempSteps.push(steps[i]);
}    
steps = tempSteps; 

//make given step active

I didn't want to issue a pull request since this is a new feature, and I'm not sure what the design/style of this js file will be, I can issue one if you'd like.

I also see a need for such a feature.

It's not implemented yet as I am wavering between having it as a additional class or (as in your solution) as yet another data attribute.

It is also connected to another the feature I need - having a possibility of displaying steps in a different order that in markup (and being get to a single step more that one time - without going back and forward).

So basically yes, the excluding will be included at some point, I'm just not sure yet how it should be done.

I see this is still open... is it still in the works?

Didn't see this before my comment in the API issue. There you have what I think is the easiest way to implement the "having a possibility of displaying steps in a different order that in markup (and being get to a single step more that one time - without going back and forward)"

About the feature requested here, I would say that the right way to do this was not to use the step class as it is not an step, but using a "background" class for example, that would be loaded into the presentation before the steps so that they are always in the background (I'm not sure if this background would be a problem when having a step deep in the z-axis, maybe a style should be applied so that they are always behind the steps.

The last reason why I would do this with another class is because this will make the selector easier.

Hi @danny

As you may have noticed, I've been working on adding a new plugin api to impress.js, and then on adding new features as plugins. It now has a skip plugin which can be used to add steps to a presentation, which will nevertheless be skipped when navigating through the presentation.

skip plugin is now merged to impress.js master
