:+1: for External scrollTarget and selection. Pretty much the last things that are keeping me from moving to 1 from .5.

Before this gets out of hand with people spamming +1 for every feature on this list, there's a subscribe button over there ->, use that to get notified of updates rather than spamming everyone who is subscribed. We all have features we need from this plugin, that's why there's a list of them in the issue description.

[nomego]

:+1: for grouping

[gertcuykens]

Is the flex height some where in the backlog because I can't fit the screen? http://jsbin.com/qiyifet/edit?html,output

[birkir]

+1 for the grid

[indolering]

DON'T POST '+1' or :+1:, USE THE SUBSCRIBE BUTTON!!!

@pdf: Gotta make it obvious : (

[kentokage]

Is there a feature where the columns are fixed? This is for a scenario where there maybe a lot of columns and you want the first one or two columns on the left fixed.

[robrez]

@knyto2 You may want to check out vaadin's "v-grid"... https://github.com/vaadin/components

demo: http://vaadin.github.io/components-examples/v-grid/columns.html

It was highlighted during this year's IO Polymer talk... https://youtu.be/fD2As5RmM8Q?t=1027

[chyyran]

What does p1 and p2 mean?

[blasten]

@RonnChyran the priorities :)

[agozie]

@robrez from my experience, vaadin v-grid becomes very laggy with a dataset of a few hundred entries. But the iron-list is butter smooth, no matter what i threw at it. I had to replace vaadin v-grid with the iron-list, though with some effort that I don't regret.

[chyyran]

@blasten That's too bad then seeing as my app relies heavily on grid :/

[jojule]

@agozie would would you give some more detail on v-grid use? It would help us to fix the problem.

[jouni]

@agozie: Indeed, a simple test case would be helpful, and details about your environment.

We’re actually doing performance profiling at the moment, trying to identify the bottlenecks.

[gertcuykens]

PS Mine is still stuk at 20 max using iron-list.git#1.0.1 ?

[agozie]

@jojule @jounik javascript req.success(json.data, json.number); once json.data is an empty array, the grid fails to load subsequent data. My application involves displaying table data for clients, some have data, others empty. Once a client without data is encountered, javascript this.$.grid.data.clearCache() fails to load data on subsequent clients. This is my main reason for dropping vaadin v-grid. The data has image and paper-icon-button fields. It gets very laggy when you scroll up and down a few times.

[jojule]

@agozie Sounds like a memory leak, not a performance problem. More details would be needed to research the issue.

To avoid hijacking the thread for things unrelated to iron list, would you be so kind to email to jouni@vaadin.com about details?

[shanika]

Any idea when Grouping + dividers will be available? or any news related to this feature will be much appreciated.

Thanks

[gertcuykens]

For me selection is only 50% completed because you can't preselect out of the box. See http://stackoverflow.com/questions/32297052/iron-list-keep-selection-highlight-on-refresh

[davidrissato]

Please, could you put "Horizontal mode" in the priority list? I hope it supports "horizontal wrap" flow.

[Wurper]

Im also very interested in any information regarding the progress on the Grouping + dividers - feature.

[GrahenKraken]

Is there any way to get an approximate ETA for "Grid"? I know I'm probably asking too much, but my app's performance hinges on it.

[rbjarnason]

+1 on Grid support :)

[nomego]

@kevinpschaaf Is there any spec for the grouping support, anything I can help out with? It's the only showstopper for us migrating our whole application to Polymer 1.0.

[Andersmholmgren]

+100 on the drag n drop reordering

[safizn]

Excellent job, thank you so much !

[Saulis]

Hate to be spamming like this, but in case someone is interested, I've been extending iron-list towards being a data grid: http://saulis.github.io/iron-data-table/

Comments, feedback, help – all would be highly appreciated.

[nomego]

I'll take the opportunity to present cosmoz-grouped-list - an approach to a layer component to support different templates for group headers and group items in iron-list: https://github.com/Neovici/cosmoz-grouped-list

This is a component central to our cosmoz-omnitable component: https://github.com/Neovici/cosmoz-omnitable

[redaready]

+100 Horizontal mode

[bobabellon]

is the backlog checklist updated? not sure if horizontal mode is implemented yet, updated to latest version of iron-list but i dont see horizontal mode in it...

[keanulee]

iron-list isn't currently under active development, so there's no timeframe for these features. Horizontal mode sounds sufficiently different that it might warrant a new element.

[davidrissato]

I wrote a small article in 2015 that says how you can achieve horizontal grid columns using iron-list:

https://easyusedev.wordpress.com/2015/10/02/polymer-how-to-iron-list-horizontal-grid/

Since iron-list is not under active development, that approach might be helpful.

[bobabellon]

@davidrisatto would that work for an infinite horizontal list? Or only if you have a definite or pre defined number of columns?

[davidrissato]

@bababellon No, that solution is more towards a vertical grid with multiple horizontal cells per line.
