Remove shinydashboardPlus dependency

[riccardoporreca]

SmaRP depends on package shinydashboardPlus for the sole collapsible panels provided by shinydashboardPlus::boxPlus().

Our current dependency on shinydashboardPlus poses the following undesired issues:

• The whole big bulk of JS and CSS associated to it code is loaded.
• It currently causes a JS error
  
• The JS and CSS has caused and can cause issues and conflicts with other components, for instance
  • when adding iframe-resizer support, see Allow embedding SmaRP into a resizable iframe #69 (f40723c)
  • with tooltips, see tooltips do not disappear on their own #54 (comment)
  • with modals, see add progress bar while report is created #50 (comment)

The suggestion is to get rid of shinydashboardPlus alltoghether by replacing boxPlus() with small custom code for creating HTML panels and adding collapsing functionality from the existing dependency package bsplus.

New custom SmaRPanel() replacing shinydashboardPlus::boxPlus() implemented in
419b158 (including removal of shinydashboardPlus package dependency). The replacement can be assessed in the app itself or in the standalone example man-roxygen/ex-SmaRPanel.R

TODOs

• Document SmaRPanel() => Done in 2da4c85.

• Address different size of tooltips, which looked better before thanks to the container: 'body' option previously set by AdminLTE's JS (formerly included via shinydashboardPlus).

  • Fixed in 9a791a1 by creating a wrapper to bsplus::bs_embed_tooltip passing container = "body" by default. This is turned into a data attribute data-container and used as tooltip option.
  • Usage of container = "body" can be reviewed as part of Review tooltips location (not mobile-friendly) #115.
